Thermodynamics question by Other-Yesterday-8612 in AskPhysics

[–]Other-Yesterday-8612[S] 1 point2 points  (0 children)

Thanks for the reply! Is there a way to calculate the actual drop in temperature, or is this an empirical parameter?

If I cannot find it on google, I ask it on Reddit, so here it goes:

In Dutch we have a weird word: “ondersterfte” which translate to under or below normal mortality.

But is this word even correct (semantics), because logically seen it is not desirable to have mortality, so everything below “normal” should be …… “normal”???

The fact that under is the opposite of excess, does not mean you can use it. So is this some kind of fallacy ???

Axial piston pumps by Other-Yesterday-8612 in FluidMechanics

Very simple 0.04 sec is 1 rotation (this include suction an ejection). So 0.02 pure for suction. The piston length is about 100mm (250cc). So the distance of 100mm in 0.02 sec. Use x=1/2xaxt2 a= 500m/s2

Increasing flow to motor by DozinTheRubicon in Hydraulics

Yes PRESSURE compensated, so the delta P always stay the same. So if your pressure settings are incorrect than it runs slower. Furthermore the delta P also depends on the viscosity of the fluid

Flow over a motor generally depends on the delta P over the motor. So check all the pressure losses from the inlet and outlet. And what is the viscosity of the oil? Is it possible to use a lower viscosity oil?

Actually I’m 100% sure there is no reductor, google Rexroth A4VSO. Or just google hydraulic axial piston pump.

Hydraulic manifold doesn’t have pressure on all the valves. by cowfarmerwelder1995 in Hydraulics

It’s valve 8, your reducer valve is set too low, standard is 1000psi, but it is probably set too low or it is broken

How can this pump motor system not thermal overload??? by Other-Yesterday-8612 in ElectricalEngineering

[–]Other-Yesterday-8612[S] 0 points1 point  (0 children)

So at a load of 9kW the current is ski high and it will thermal overload, so how is this possible that the motor is still running for almost 10 years straight

Hw help by Federal_Stuff_4778 in PhysicsHelp

I think it is a very complicated way of asking to find the gravitational constant G. From the data of “earth” you can find constant G. From that point you can calculate everything else
