Water flows at low speed through a circular tube with inside diameter of 2 in. A smoothly contoured body of 1.5 in. diameter is
held in the end of the tube where the water discharges to atmosphere. Neglect frictional effects and assume uniform velocity profiles at each section. Determine (a) the pressure measured by the gage and (b) the force required to hold the body.

Answer:
471.43MW
Explanation:
the rate of heat transfer to the power plant is determined from the thermal efficiency equation
Qh =
Qh = 600 MW / 0.56
Qh =1071.43MW
The rate of heat transfer to the river is determined from the first law related to heat engine
QL = Qh - Wout
= 1071.43 - 600
= 471.43MW
the heat will be lost to the surrounding air as it passes through pipes and other surrounding components
