Question: Listed below, as functions of axial distance, are the radius, mass velocity, temperature, and pressure inside a supersonic nozzle. The fluid is air. It is desired to maintain the nozzle surface uniformly at 200°C. Calculate the necessary heat flux along the nozzle surface. Assume that a turbulent boundary layer originates at the start of the nozzle.
