Q.1 Heat exchangers are open systems used to cool down and/or heat up certain fluid streams. Steam at a rate of 60 kg/h, at 200 C, and 1 bar enters the tube side of a heat exchanger. The steam is used to heat cold water flowing on the shell side (outside tubes). The steam leaves as saturated liquid. Neglect the pressure drop of the steam on the tube side and the water on the shell side of the heat exchanger. How much heat must be transferred from the steam to the water side
