Steam is to be condensed on the shell side of a 1-shellpass and 8-tube-passes condenser, with 60 tubes in each pass at \( 90^{\circ} \mathrm{F}\left(h_{f g}=1043 \mathrm{Btu} / \mathrm{bm}\right) \). Cooling water \( \left(c_{p}=1.0 \mathrm{Btu} / \mathrm{bm} \cdot{ }^{\circ} \mathrm{F}\right) \) enters the tubes at \( 55^{\circ} \mathrm{F} \) and leaves at \( 70^{\circ} \mathrm{F} \). The tubes are thin walled and have a diameter of \( 3 / 4 \) in and length of \( 5 \mathrm{ft} \) per pass. If the overall heat transfer coefficient is \( 600 \mathrm{Btu} / \mathrm{h} \cdot \mathrm{ft}^{2} \cdot{ }^{\circ} \mathrm{F} \), determine \( (a) \) the rate of heat transfer, \( (b) \) the rate of condensation of steam, and (o) the mass flow rate of cold water.
