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 flow rate of the steam is 2.6 x10⁵ kg/hour. The cooling water enters the heat exchanger at 5 MPa and 15^oC (state 3) and exits at 38^oC at the same pressure (state 4).

The cooling water can be treated as an incompressible liquid. Neglect stray heat transfer and neglect kinetic and potential energy effects. As well, assume the system is operating under steady-state conditions. Do the following:

a) Draw a schematic of the system and locate the four state points on a T-v diagram (use the numbering scheme given in the above paragraph).

b) Determine the mass flow rate of cooling water in kg/s

c) Determine the rate of heat transfer between the steam and the cooling water in MW.
