Yes you are right, but I think you look at my system too strictly and too literally, so my point of original question is lost. If...

My configuration can achieve P2 lower than atmospheric pressure?

When pump start working, does static pressure rise after the pump(outlet) or only rise dynamic pressure? If yes, than we must add this...

a) initial pressure is 200kPa, open valve fill the pressure and close the valve. Pump is here for circulation not pressure b)from pump...

If have close pipe system with water inside pressurized at P1= 200 000Pa absolute, density 1000kg/m3, wider pipe diameter=2cm...

Isn't wierd that pressure is lower than atmosperic pressure, so if you drill hole in that part of turbine housing, air will be sucked in...

If I use data from plot, density=0.4kg/m3, minimum total pressure(blue)= 1.06e+05Pa, velocity=325m/s, using compressible equations I get...

Is total pressure from my post #4 absolute or guage pressure?

What is solution to find pressure P2?

Can you elaborate more, maybe put some power curves plots that support that?

Which engine have wider "power band", more average power around max power rpm-s(rpm range that car use for max acceleration), high revs...

When I increase airlfow speed v1, pressure in contraction drop more and more, so at some point fall even below 0 Pa absolute, but this...

I refer at turbine not compressor. Low pressure at turbine and compressor is not good, becuase it will suck engine oil. @boneh3ad...

This is the force applied by the driving wheels to the road, plotted against road speed. Because F = m · a ; it also represents vehicle...

This is question for fluid mechanics. Static pressure in the exhaust manifold(turbo car engine) is usually 1.2 to 2.5 times higher than...
