МЕСН 2344 QUIZ 3 Buring steady-state operation, a gearbox receives 60 kw through the input shaft and delivers power through the output shaft as shown in Figure 1. For the gearbox as the system, the rate of energy transfer by convection is Q = -hA(T, – T) where h = 0.171 kW/m² · K is the heat transfer coefficient, A =1.0 m² is the outer surface area of the gearbox, T = 300 K is the temperature at the outer surface, and T; = 293 K is the temperature of the surrounding air away from the immediate vicinity of the gearbox. For the gearbox, evaluate the heat transfer rate and the power delivered through the output shaft, each in kw T;= 203 K Input shaft Gearbox Output shaft Outer sarface A= 10 m Figure 1
