    Undergrad What is the velocity of air through a 6mm pipe at 3 bar pressure?

    sounds like a gasdynamics. 3 bar in a compresser? Mach 1 at outlet.

    Confusion about calculation of aerodynamic moments

    need more information like page where to find in that book?

    Undergrad What is the velocity of air through a 6mm pipe at 3 bar pressure?

    if I understand your question right v_out = [2(p_in - p_out)/airdensitiy + (v_in)^2]^0.5

    Solving equation with numerical analysis

    need hint/help or perhaps a solution :smile: Equations are from Propeller Blade Theory. I´m trying to figure out how to determine \epsilon_i from equation 2.3.25 my first thought was to substitute sin(A+B) = sinA*cosB + cosA*sinB... it says quote: " This equation is easily solved...

    Thermodynamic cycle of jet engine

    Brayton Cycle. Parameters for designing : Combustion chamber temperature ( you do not want to damage your turbine ), Compression ratio. I think those two are quite important.

    Wing transition to turbulent flow

    the reason you want turbulent flow is to push back airfoil separation on the cross section of your wing. turbulent flow has higer energy than laminar flow which prevents separation happening too early. turbulance flow generates more friction drag (than laminar flow) but friction drag ist very...
