Saturated steam at 100 °C condenses in a shell-and-tube heat exchanger (one shell pass, two tube passes) with a surface area of 0.5 m2 and an overall heat transfer coefficient of 2000 W/m2·K. Water enters at 0.5 kg/sec and 15 °C. Determine: a. the outlet temperature of the water (in °C) b. the rate of steam condensation (in kg/sec).
