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.

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.
