The area velocity relationship for compressible fluid flow is
The speed of sound in oxygen at a pressure of 100 kPa (absolute) and 27°C is (Take R = 260 J/kg K and K = 1.4)
An airplane is flying at an altitude where the pressure is 20 kPa (absolute) and the density is 0.28 kg/m3. If the plane has attained a mach number of 1,8, what is the speed of plane in km/hr?
A rocket is found to have a speed of 2160 km/hr in air at a temperature of -40°C. What is approximate Mach angle? [Take R = 287 J/kg K and K = 1.4]
