If have close pipe system with water inside pressurized at P1= 200 000Pa absolute, density 1000kg/m3, wider pipe diameter=2cm... -
gen x replied to the thread Local pressures in turbocharger housing?.Isn't weird that pressure is lower than atmosperic pressure, so if you drill hole in that part of turbine housing, air will be sucked in...

gen x replied to the thread Local pressures in turbocharger housing?.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...

gen x replied to the thread Local pressures in turbocharger housing?.Is total pressure from my post #4 absolute or guage pressure?
-
gen x replied to the thread Problem with Bernoulli calculation.What is solution to find pressure P2?
-
gen x replied to the thread Turbo vs naturally aspirated engine power band width around peak power.Can you elaborate more, maybe put some power curves plots that support that?
-
gen x posted the thread Turbo vs naturally aspirated engine power band width around peak power in Mechanical Engineering.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...

gen x replied to the thread Local pressures in turbocharger housing?.I refer at turbine not compressor. Low pressure at turbine and compressor is not good, because it will suck engine oil. @boneh3ad...

gen x reacted to Baluncore's post in the thread Undergrad Calculate acceleration from power/torque graphs with
Like.
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...

gen x replied to the thread High School Why higher speeds need more power if the backward force is the same?.correct
-
gen x replied to the thread High School Why higher speeds need more power if the backward force is the same?.But is this 100% correct? If you hold 20kg weight in one position, you consume more energy than if you dont lift anything?
-
gen x replied to the thread High School Why higher speeds need more power if the backward force is the same?.What are shortcuts in case of engine? So engine that have more area under power curve in operating rpm interval where you shift gears...

gen x replied to the thread High School Why higher speeds need more power if the backward force is the same?.When we talk about average power/torque/force, if I want to find average power under power curve in some rpm interval, I need to...
