A shell and tube heat exchanger uses 650 tubes of 5/8 in B.W.G 18 (do = 0.625 in and d i = 0.527 in)

A shell and tube heat exchanger uses 650 tubes of 5/8 in
B.W.G 18 (do = 0.625 in and di = 0.527 in) and 7.5 ft per pass.
Tubes are stainless steel. The heat exchanger has one shell and two-tube passes
per shell. Cold water enters the tubes at a velocity of 6.818 ft/s and a
temperature of 75 F. Hot water enters the shell at 195 F and at a rate of 2.5E6
lbm/h. The fouling factors happen to be equal for both tube and shell sides, fi
= fo = 0.0005 h·ft2 ·F/Btu. Find Th,out, Tc,out,
Uo, _, total rate of heat transfer, and the tube-side pressure
drop.
