An oil at a flow rate of 49600 lb / h is cooled from 358 F to100 ˚F on the pipe side of a 2-4 shell-tube heat exchanger. At aflow rate of 233000 lb / h used for cooling, water enters the shellside at 90 ˚F and exits at 120 F. The inner diameter of the heatexchanger used is 35 in and there are 454 1 in OD 12 BWG copperpipes with a length of 12 ft. The pipes are placed in a 1 inchsquare arrangement. The distance between the 25% obstacles used is7 in. Examine whether the heat exchanger can be used for such asystem, neglecting the pipe inlet effects, viscosity corrections,fouling factors and pipe wall thickness resistance.

For oil: μ= 1,12 cP, Cp= 0,545 Btu/lb.˚F, k= 0,2Btu/ft2.h.˚F

For water μ= 0,73 cP; Cp= 1 Btu/lb.˚F, k= 0,362Btu/ft2.h.˚F
