Steam generators are a type of heat exchanges that are used inpower plants to generate steam at desired pressure andtemperature (Fig. Q1.b). In a steam generator, saturated liquidwater at 30°C enters a 60-mm diameter tube at the volume flowrate of 12 L/s. After exchanging heat with hot gas, the waterchanges to steam and leaves the generator at a pressure of 9 MPaand a temperature of 400°C. During this process, the diameter ofthe water/steam tube does not change. Where necessary, assume air as an ideal gas and consider R = 287J/(kg.K), Cp = 1005 J/(kg.K), Cv = 718 J/(kg.K). (i) Calculate the steam mass flow rate and inlet velocity of the steam? (ii) What is the exit velocity of the steam? (iii) Calculate the rate of heat transfer (in MW) required tochange the phase of liquid water to steam.
Q2: A nozzle is a device for increasing the velocity of steadily flowing stream of fluid. At the inlet to a certain nozzle the enthalpy of the fluid is 3025 kJ/kg and the velocity is 60 m/s. At the exit from nozzle the enthalpy is 2790 kJ/kg. The nozzle is vertical with a 0.5 m height; ignore the heat loss from it. Find the velocity at the nozzle exit and the rate of flow of fluid if the inlet area is 0.1 m² and the specific volume at inlet is 0.19 m³/kg.
