Average Heat Transfer Coefficients Fig 14a1 Ten Thousand Pounds Per

Average heat transfer coefficients (Fig. 14A.1), Ten thousand pounds per hour of an oil with a heat capacity of 0.6 Btu/lbm F is being heated from 100°F to 200°F in the simple heat exchanger shown in the accompanying figure. The oil is flowing through the tubes, which are copper, 1 in. in outside diameter, with 0.065-in. walls. The combined length of the tubes is 300 ft. The required heat is supplied by condensation of saturated steam at 15.0psia on the outside of the tubes. Calculate h1, ha, and hIn for the oil assuming that the inside surfaces of the tubes is at the saturation temperature of the steam, 213°F
