4. The following heat exchanger uses 10 kg/s of hot air to heat and boil liquid water into saturated steam at 500 kPa. (a) Find the steam flow (kg/s) (b) Determine whether the process is allowed by the second law (Answer: It is not!) (c) On the surface, the process looks OK as Tair>Twater at both the inlet and outlet. You should be able to see the problem if you sketch the air and the water temperature profiles as you move left to right through the exchanger. (Hints: The air will be essentially a straight line, while the water will not. For the water, think about what happens when it is changing phase.) This is called a pinch point violation, and it is a very important design consideration in advanced combined cycle systems and in nuclear power plants.

A steam condenser receives 10 kg per second of steam with an enthalpy of 2570 KJ/kg. Steam condenses into liquid and leaves with an enthalpy of 160 KJ/kg, if cooling water passes through the condenser with temperature increases from 13oC to 24oC. Calculate the cooling water flow rate in kg/sec. pls dont skip anything show all solution including conversion of units
(b) A heat exchanger as shown in Figure 1 is used to cool water flowing in at 1 kg/s water, 10 kPa and quality 0.95 to saturated liquid at 10 kPa. The cooling fluid is water taken from a lake at 20°C and it exit the heat exchanger at 30°C. Calculate the flow rate of cooling water. Assume that the heat exchange is well insulated and there is no heat loss. Lake water Figure 1: Heat exchanger
