Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.

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.
An air-cooled condenser has an h value of 30 W/m2-K based on the air-side area. The air-side heat transfer area is 190 m2 with air entering at 27°C and leaving at 40°C.

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.(i) Calculate the steam mass flow rate.
