A refrigeration truck is traveling at 130 km/h on a desert highway where the air temperature is

Question:

A refrigeration truck is traveling at 130 km/h on a desert highway where the air temperature is 50°C. The body of the truck is idealized as a rectangular box 3 m wide, 2.1 m high, and 6 m long, at a surface temperature 10°C. Assume that

(1) The heat transfer from the front and back of the truck is neglected

(2) The stream does not separate from the surface

(3) The boundary layer is turbulent over the whole surface. Calculate the required cooling rate of the refrigeration unit
