Acubic transmission casing whose side length is 25cm receives an input from the engine at a rate of 350 hp. if the vehicle's velocity is such that the average heat transfer coefficient is 230 w/m'k and the efficiency of the transmission is n=0.95 (i. e. the remainder is heat), calculate the surface temperature if the ambient temperature is 15°c. assume that heat transfer only occurs on one face of the cube. note: 1 hp=745 w
