Answer:
C) 0.182 W
Explanation:
The effective conductive section is:

The thermal conductivity of stainless steel is
k = 18 w/(m * K)
Heat conduction in a rod follows this equation:

Answer:
Power output, 
Given:
Pressure of steam, P = 1400 kPa
Temperature of steam, 
Diameter of pipe, d = 8 cm = 0.08 m
Mass flow rate, 
Diameter of exhaust pipe, 
Pressure at exhaust, P' = 50 kPa
temperature, T' = 
Solution:
Now, calculation of the velocity of fluid at state 1 inlet:




Now, eqn for compressible fluid:

Now,




Now, the power output can be calculated from the energy balance eqn:
