Determine the mass flow rate of cooling water : A shell-and-tube heat exchanger is used to cool a flow of steam using a stream of cooling water. The steam enters the heat exchanger at 0.1 bar and a quality of 91% (state 1), and exits as a saturated liquid at the same pressure (state 2). The mass f..
