the slip in a centrifugal pump is in theory although there is probably some.
the point is, there IS NO IDEAL FLUID
did the 90,000psig have an affect, hummmm sure it did, especially when it is WAY more pressure than a mile deep ocean.

?
can water change density

hummmmm

what happens when you make ice?????
ideal fluid???? i do not think so.
if they can make measurement to the micron, no hill for a stepper to measure pressure.
you only know a fraction of what the government has access to, my late uncle carlos worked in the nuke sub core and it is unreal what our capabilities are.
for instance, if you fire a nuke torpedo, they guide it via a extremely fine wire and turn around and get out of dallas so as not to be in the sonic zone, when the nuke get into range, the wire is severed and onboard electronics take over, shoot doesn't even have to hit the target.

closed system, hummm, hardly!
the principle applies to all pumps. https://blog.craneengineering.net/ho...ent-pump-curve
does hd do all of their R&D, hummm, hardly
why do work that already exists.
for instance, you want to make a music room for that steel guitar so you use a program that generates the necessary parameters to get the effects you want, hummm, someone else's work or do you fly by the seat of your pants as probably how the program got made anyway, from prior knowledge.
you can buy a pretty much tricked out crate engine and you trust it, why???
well is is based off prior engineering.
did hd make hundreds of pumps before settling on one???? hummm, i doubt it, why, because they made changes because the prior engineering which the pump was based on had issues.

frivolous to say the least
why does ford tail pipe burn neutral and the chevy black???? if both trucks use O2 control, what is the diff????
if the burn is supposed to be complete, why is there soot????
why is that barn red and the other green????
who said it was green?? just because someone in the past said so???
life goes on.

IF you really want to get serious, go SCADA!!!
that prized pressure gauge you have MUST follow the laws of averages. get a test mule and install flow meters and pressure transducers and then and ONLY then will you ever come close to checking the engineering.
that said, did HD do so, hummm, hardly!!!

Bustert, your drawing in post#22, I was not considering inlet head and had flow pressure on the brain.
Your right, the pressure is the same at the bottom, if they are all are the same temp and all are the same liquid.
My perspective was off.

That got me to thinking about tank head though.
So I did some figuring...

The Hydrostatic Pressure of a fluid at a given depth does not depend upon the total mass or total volume of the liquid.
Because of ease of visualizing a column height of a known liquid, it's become common practice to state all kinds of pressures in column height units.
Pressures are often measured by manometers in terms of a liquid column height.

The pressure exerted by a static fluid depends only upon the depth of the fluid, the density of the fluid, and the acceleration of gravity.
The pressure in a static fluid arises from the weight of the fluid and is given by the expression: P = pgh.

P = static fluid pressure
ρ = fluid density
g = acceleration of gravity
h = height of fluid

Example:
Relative Density (same as specific gravity) of Mobile 1 V-twin 20w50 is (.87) at 60°F (15.6°C).
Specific Gravity of water is (1.0) at 60°F (15.6°C).
For the example below, we'll use these figures:
Relative Density: (.87)
Standard Gravity: (32.174 ft/s²) - feet per second squared
Height: (1.23ft) - as eyeballed on a 1998 1200S, 14.75“

Example calculations: P = pgh
P = .87 x 32.174 ft/s² x 1.23 ft = 34.43 ft/s² (rounded figures)
Converting ft/s² to in/s² : 1 psf = 0.00694 psi (34.43 x 0.00694 ) = 0.239 psi (rounded figures)

Mathing works if I plugged the numbers in right.
So by these figures, the oil tank head as seen at the oil pump inlet is 0.24 PSI (static pressure).
This is assuming the oil level is at 60°F and at the top mark on the dipstick.
Oil density lowers (gets lighter) when heated. So the .87 figure above may go down to around to .82 at 212°F (100ºC).
In that case, the static pressure would go down to around .225 PSI at operating temp.

Lowering the oil level to the low mark on the dipstick will lower the pressure at the oil pump.
The mark is there as a minimum oil level to attain enough pressure at the pump to keep down cavitation in the oil pump.
A change in location elevation from sea level will change the pressure at the oil pump.
The roughness of the feed hose ID will lower pressure at the pump due to the affects of friction.
Kinks in the feed hose or internal shrinkage of the inside walls of the feed hose will lower pressure at the oil pump.
Changing the inlet fitting to a smaller ID will lower pressure on the hose side of the fitting.
The static pressure at the inlet is changed further upon vacuum from the oil pump inlet.
The hose fitting is a restriction where flow (from vacuum)of pump gear action lowers static on the hose pressure.



Reference:

Specific Gravity

Specific gravity is the heaviness of a substance compared to that of water, and it is expressed without units because it is simply a ratio.
In the metric system, specific gravity is the same as in the English system.
If something is 7.85 times as heavy as an equal volume of water (such as iron is) its specific gravity is 7.85.
Its density is 7.85 grams per cubic centimeter, or 7.85 kilograms per liter, or 7.85 metric tons per cubic meter.
In relationship to liquids, the term specific gravity is used to describe the weight or density of a liquid compared to an equal volume of fresh water at 4°C (39° F).
Specific Gravity of water at 4°C (39° F) has been assigned a value of one (1).
If the liquid you are comparing will float on water it has a specific gravity of less than one (1).
If it sinks into the water, the specific gravity is more than one.

There is no correlation between viscosity and specific gravity.
Specific gravity can be measured with a hydrometer.
It consists of a glass cylinder with a rubber bulb on top, and a float positioned inside the glass tube.
The float is calibrated to float on fresh water.
If the fluid you are testing has a higher specific gravity, the float will raise in the liquid.
And at a lower specific gravity it will sink lower in the liquid.
This is the same type instrument used to tell if an automobile battery is fully charged.
Or another version of this instrument tells the concentration of anti-freeze in an automobile radiator.
You can observe the little balls floating in the tube.

Standard Gravity

According to Wikipedia, standard gravity is the nominal gravitation acceleration of an object in a vacuum near the surface of the Earth.
Standard Gravity was established at the third General Conference on Weights and Measures in 1901.
The standard gravity on Earth is 9.80665 m/s² (meters per second squared), or 32.174 ft/s² (feet per second squared).

However, standard gravity only applies to an object or body at sea level and geodetic latitude of 45 degrees.
This figure will change somewhat depending on the elevation above sea level where you are.
So, for more accurate result, calculating your own local gravity would be better.

Yes, oil, like water, flows downhill.

hummmm???
taking out aerodynamics, which will fall faster a pound of rocks or a pound of feathers??
you forget one thing
yes, oil will change density just like water, but if you put one pound of oil into the tank at 60* and heat it to 200* will it still weigh one pound???
mass or weight changes at temperature changes, when VOLUME IS CONSTANT!
since mass changes and expands with temperature, the level rises does it not???
however, over-all there is still only one pound of oil!!!

There is an equation I ran across that compares volume (not weight) of a gallon when heated to 5 quarts.....
But the oil gets lighter per square in.

I had a bunch of stuff already written and forgot to save and then had a power spike....lost it.
But a gallon of oil average is about 8 pounds (mass, not fluid oz).
I did not expect 3 quarts (6 pounds) to only exert 0.24 PSI at the pump.
Of course, the next topic is cavitation.

Rocks/feathers all the same, yes.
And in the equation, you only change the density for heat changes.
The speed (32.174 ft/s² ) stays constant.

And the density will lower slightly more than I stated as I used the Celsius chart by mistake.
But PSI with the F chart still remains at 22PSI when doing the equation.

This chart is from Engineering Toolbox.

It doesn't matter if you have 3 qts or 12 qts (6 lbs or 24 lbs) all that matters is the height above the pump. You can sit and do all the calculating you want but everything cancels out and leaves you with a weight/area figure which psi is.

Just go away Tomcatt.
Everybody will breath a sigh of relief.

edit:
I can't say anything around you without you trying to suppress me.
You threw physics in my face on another thread like you actually knew what the xxxx you were talking about.
THIS THREAD WAS STARTED BECAUSE OF YOU.
Yep, this a memorial "Go xxxx yourself" thread in your honor.
I'm tired of you trying to turn everybodys bike into yours.
I'm tired of you spouting bullshit to those that don't know any better.
You, like some others have the stupid idea that I'm trying to be king of the mountain.
Your jealousy of my curiosity is funny on face value.
But trouble is, you are ruining it for others.
I don't have to post a DAMN thing on this forum.
I can just post to the SP and move on.
You think I give two shits what you think?

THIS IS MY THREAD ASSHOLE, GO MAKE YOUR OWN.
I've wanted to run down the pressure system for a while now but haven't had the opportunity.
You gave me incentive.
For the record, I stated to begin with that I'm not preaching here.
I'M LEARNING. I've already changed my opinion on several things so far in this thread.
I learn by doing the work. I don't learn from listening to other's bullshit like you.

SO PLEASE LEAVE THIS THREAD AND ME THE xxxx ALONE.
I learn by research, writing and thinking.
You learn by repeating.
Let me do my own thing and you go do...…. whatever the xxxx it is you do here.

Mods can delete this post but please let Tomcatt the Asshat read it first.
SHeeeez, get a xxxxing life.

Then try actually learning. You're not doing very well so far. All I did was explain the math involved that you over complicated. Edit, since you edited your post: If the weight of the oil, 6 lbs, wasn't an issue why did you even mention it? It "surprised you" that 6 lbs of oil made only a ~1/4 psi pressure? It makes no difference how much oil is up there, the weight is irrelevant, just how high matters. No surprises...

Too bad this is what you resort to to avoid meaningful discussion that might let others learn even if you just want to rationalize.

Name calling is what people who can't justify what they're saying resort to.
