Air at 27°C, 1 atm flows parallel to a flat plate, which is electronically heated. The plate is 0.5 m long in the direction of f
low. The uniform heat flux from the plate to the air is 3,000 W/m². A trip wire placed at the leading edge of the plate ensures that the boundary layer is turbulent over the entire plate. A thermocouple mounted at the trailing edge of the plate records a temperature of 127°C. Consider the following:
a) Determine the local Nusselt number Nuy at the trailing edge of the plate.
b) Calculate the Reynolds number Rex at the trailing edge of the plate.
c) Evaluate the air free stream velocity (m/s).
