Average heat transfer coefficients (Fig. 14A.1), Ten thousand pounds per hour of an oil with a heat capacity of 0.6 Btu/lb_m 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, h_a, and h_In for the oil assuming that the inside surfaces of the tubes is at the saturation temperature of the steam, 213°F
