Question: A flat plate is placed in a supersonic wind tunnel with air flowing over it at a Mach number of 2.0, a pressure of 25,000

A flat plate is placed in a supersonic wind tunnel with air flowing over it at a Mach number of 2.0, a pressure of 25,000 N/m2, and an ambient temperature of ??15?C. If the plate is 30 cm long in the direction of flow, calculate the cooling rate per unit area that is required to maintain the plate temperature below 120?C.GIVENHigh speed air flow over a flat plateMach number (M) = 2.0Air pressure (P) = 25,000 N/m2Ambient temperature (T??) = ??15?C = 258 KPlate length (L) = 30 cm = 0.3 mASSUMPTIONSSteady stateAir behaves as an ideal gasNegligible radiative heat transferAir flows over only one side of theplate
