(25 pts) In a Lunar nuclear plant water (p-1000 kg/m' and C-4180 J kg-C] is a scarce commodity. Because of this, all water must be conserved. So in this plant

the condensate from the main heat exchanger is collected and passed through a heat exchanger to further cool it. The condensate initially enters the shell and tube heat exchanger at 43°C with a flow rate of 21.4 kg is and is cooled with another water stream entering the heat exchanger at 18°C with a flow rate of 18.9 kg/s. The hotter fluid passes through the shell side of the heat exchanger which has a 43.8 cm outer diameter and the cooler fluid passes through 224 tubes with a 1.9 cm outer diameter. Assume that the overall heat transfer coefficient is 1980 W/m-°C. Determine the outlet temperatures of both of these fluids from the shell and tube heat exchanger if the tubes are arranged in a triangular pitch and have a length of 4.9 m.
