In a power plant, the inlet water has a
velocity of 100 ft/s and an elevation of 80 ft
above the outlet of the plant. The outlet
water has a velocity of 5 ft/s. How much
work can be extracted by the power plant
per unit mass of water passing through the
system? The enthalpy of the outlet water
may be assumed identical to the enthalpy of
.the inlet water
