A Carnot engine operating between energy reservoirs attemperatures 300 K and525 K produces a power outputof 1040 W. What are each of thefollowing?
The rate of Heat input? in W.
The rate of Heat output? in W
For the one dimensional conduction problem given below, Ti and Toare the temperatures of the inner and outer surfaces. Determine therate of conductive heat transfer Q when A = 10m2:a. Ti = Tob. Ti = 20oC, To = 10oC, k = 0.35 W/m*Kc. Ti = 20oC, To = 0oC, k = 0.35 W/m*Kd. Ti = 20oC, To = 0oC, k = 0.1 W/m*K
10 cm long, 2 cm diameter copper rod (k = 380 W/m-K) is exposed to an environment at 25°C The base temperature of the rod is maintained at 200°C. The heat transfer coefficient between the rod and the surrounding air is 15 W/m2K. Determine the heat transfer rate from the rod to the surrounding air (W) when it is considered as a fin.
a) 10.5 W
b) 14.5 W
c) 12.3 W
d) 20.3 W
e) 16.8 W
