Extracted text: b) Steam generators are a type of heat exchanges that are used in power plants to generate steam at desired pressure and temperature (Fig. Q1.b). In a steam generator, saturated liquid water at 30°C enters a 60-mm diameter tube at the volume flow rate of 12 L/s. After exchanging heat with hot gas, the water changes to steam and leaves the generator at a pressure of 9 MPa and a temperature of 400°C. During this process, the diameter of the water/steam tube does not change. Steam out Gas out Hot gas in Liquid water in Fig 2. Schematic of the steam generator in Q1.b. (i) Calculate the steam mass flow rate (ii) What is the inlet velocity of the steam? (iii) What is the exit velocity of the steam? (iv) Calculate the rate of heat transfer (in MW) required to change the phase of liquid water to steam.
