A shell and tube steam condenser is to be constructed of 2.5 cm O.D., 2.2 cm I.D., single
pass horizontal tubes with steam condensing at 54°C on the outside of the tubes. The
cooling water enters at 20°C and leaves at 36°C at a flow rate of 1 kg/sec. The heat transfer
coefficient for the condensation of steam is 7900 W/(m².°C). Calculate the tube length. If
the latent heat of condensation is 2454 kJ/kg, calculate the condensation rate per tube. The
properties of water are as follows:
Specific heat 4180 J/(kg.°C)
Viscosity 0.86 x 10-3 kg/(m.sec)
Thermal conductivity 0.61 W/(m.°C) ·
The heat transfer coefficient for turbulent flow in a pipe may be determined by
Nu = 0.023 Re0.8 Pr0.4
