Transcribed Image Text:
During one phase of the separation of crude oil into its components, the oil is to be heated by
water in a 1-4 shell and tube heat exchanger. The oil has a flow rate of 110,000 lbm/hr, and it
enters the heat exchanger at 120°F. Water enters the exchanger at a flow rate of 66,000 lbm/hr
and a temperature of 180°F. It is proposed to use an exchanger having a shell inside diameter of
234-in. and containing 1-in.-OD tubes, 13 BWG, laid out on a 1/4-in. square pitch. The 192 tubes
are 12-ft long, and the exchanger contains six baffles. Determine expected outlet temperatures
and pressure drops when the exchanger is new. Route the oil through the tubes, and assume
that oil has the following properties:
Cp = 2050 J/(kg-K)
p=34cp
p = 740 kg/m³
kp=0.132 W/(m·K)
