The condenser of a steam power plant operates at a pressure of 0.95 psia. The condenser consists of 144 horizontal tubes arranged in a 12 * 12 square array. Steam condenses on the outer surfaces of the tubes whose inner and outer diameters are 1 in and 1.2 in, respectively. If steam is to be condensed at a rate of 6800 lbm/h and the temperature rise of the cooling water is limited to 8°F, determine (a) the rate of heat transfer from the steam to the cooling water and (b) the average velocity of the cooling water through the tubes.

Question
The condenser of a steam power plant operates at
a pressure of 0.95 psia. The condenser consists of 144 horizontal
tubes arranged in a 12 * 12 square array. Steam condenses
on the outer surfaces of the tubes whose inner and
outer diameters are 1 in and 1.2 in, respectively. If steam is
to be condensed at a rate of 6800 lbm/h and the temperature
rise of the cooling water is limited to 8°F, determine
(a) the rate of heat transfer from the steam to the cooling
water and (b) the average velocity of the cooling water
through the tubes.
