Energy transfer in mechanical systems During steady-state operation, a mechanical gearbox receives 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: Q = −hА(T₂ — Tƒ) 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, Tb = 300 K is the temperature of the outer surface, and Tƒ= 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.
