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...

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?.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...

gen x replied to the thread High School Why higher speeds need more power if the backward force is the same?.Car acceleration decrease when speed rise (even if aero/tire drag is zero), because thrust force decrease. Torque at wheels are smaller...

gen x replied to the thread High School Why higher speeds need more power if the backward force is the same?.In case of bike, lets say my foot push on pedals only in half circle, when I am above pedal so my weight ( mg) make force on pedals. How...

gen x replied to the thread High School Why higher speeds need more power if the backward force is the same?.When I decrease F and use higer gears ratio, I can incease my speeed, but my power still remain the same. Is my example with horse...

One thing is work performed by the horse, and a different one is the time in which that work is done. Less time requires greater power...
