Energy transfer in mechanical systems 70 KW of input power through the input shaft and delivers power through the output shaft. Considering the gearbox as a thermodynamic system, the rate of convection heat transfer generated during its operation is defined by: During steady-state operation, a mechanical gearbox receives Q = -hA(T, – T;) where h = 0.171 kW/m2-K is the convection heat transfer coefficient, A = 1.0 m² is the outer surface area of the gearbox, Ti = 300 K is the temperature of the outer surface, and T;= 293 K is the temperature of the surrounding air. For the gearbox, evaluate the heat transfer rate, Q, and the power delivered through the output shaft, W.
