To do this task a stream of high-pressure steam available at 40 bar and 400°C is used, as shown in the following figure. The entire system is well insulated, as shown. It is undesirable for the steam to condense in the heat exchanger tubes. Assume the pressure of each stream stays constant as it flows through the heat exchange What is the minimum volumetric flow rate, in m3 /s, required of the inlet steam to keep it from condensing at the exit?

Water vapor with a flow rate of 20000 kg / h enters the condenser of a power plant at a pressure of 20 kPa and 95% dryness. In the condenser, there is heat transfer to the river water flowing through the pipes. The temperature rise of the river water is limited to 10 ° C to prevent thermal pollution. Since the state of the water at the condenser outlet is a saturated liquid at 20 kPa pressure, what is the flow rate of the cooling water?

HW Linde process is used for air liquefaction. The high-pressure gas leaving the compressor is at 120 bar and is cooled to 306 K (516 kJ/kg) before it is sent through the heat exchanger where it exchanges heat with low pressure gas leaving the separator at 2 bar.
