A small steam condenser is to be designed to condense 0.8 kg/min steam at 80 kN/m2 with cooling water at 290 K. If the exit temperature of the water is not to exceed 320 K, calculate the area required for a shell-and-tube heat exchanger with the steam making one shell pass and the water making two tube passes. The overall heat-transfer coefficient is 3000 W/m2 ·K.
