A stream of CO2 at pressure 1 bar, flowing at 10 mol/s, from 150°C to 300°C is to be heated ina counter current heat exchanger. To do this task a stream of high-pressure steam available at 40bar and 400°C is used, as shown in the following figure. The entire system is well insulated, asshown. It is undesirable for the steam to condense in the heat exchanger tubes. Assume thepressure of each stream stays constant as it flows through the heat exchangeWhat is the minimum volumetric flow rate, in m3 /s, required of the inlet steam to keep it from condensing at the exit?

1) Water vapor with a flow rate of 20000 kg / h enters the condenser of a power plant at a pressure of 20 kPa and a dryness degree of 95 percent. 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 saturated liquid at 20 kPa pressure, what should be the flow rate of the cooling water.

You, a process design engineer, are tasked to build a powerplant with a net output of 1 MW. First, in an industrial boiler, coal is burned to heat and pressurize 1.6 kg/s of water pumped from an underground reservoir (25 oC, 1 atm) to High Pressure Steam (44 atm, 450 oC). The industrial boiler is insulated, but due to the high temperatures and the nature of the process there are inevitably heat losses. As such, the total heat losses of the whole system is around 20% of the heat from the coal. The High-Pressure Steam, moving at a linear velocity of 70 m/s, is then used to drive a turbine. The low pressure steam from the turbine is used to preheat the boiling water and then released to the atmosphere as saturated steam (100oC and1atm) at a velocity of 10 m/s via an exhaust 10 m above the turbine inlet. How much heat is needed for the powerplant? Use the following values of enthalpy: Water from reservoir 25oC; 1atm H=104.93 kJ/kg High Pressure Steam 450oC; 44atm H=3324.63 kJ/kg Low…
