Repeat Prob. 10–79E for the case of 32 horizontal pipes arranged in a rectangular array of 4 pipes high and 8 pipes wide.
Data from problem 79
Saturated steam at 95°F is condensed on the outer surfaces of an array of horizontal pipes through which cooling water circulates. The outer diameter of the pipes is 1 in and the outer surfaces of the pipes are maintained at 65°F. Determine
(a) The rate of heat transfer to the cooling water circulating in the pipes
(b) The rate of condensation of steam per unit length of a single horizontal pipe.
