1 kg of steam at initial conditions of 5.1 MPa and 370 °C expands in a turbine until it becomes saturated. It is withdrawn and reheated to 340°C. After further expansion in the turbine to 160 , part of the steam is extracted for feedwater heating. The remaining steam expands to the condenser pressure of 0.018 MPa. find Wnet, Ec, Ee and the ideal steam rate. Remember, 1. For values taken from the steam tables: Use them as is, do not round off. 2. For values obtained by interpolation and final answers obtained by solving, use FOUR (4) decimal places. 3.

In a refrigeration cycle, the refrigerant gains heat in the evaporator and in thesuction line. In a certain refrigeration system, R-134a gains 67.8 Britishthermal units per pound (Btu/lb) in the evaporator. It then gains 2.5 Btu/lb inthe suction line. Find in Btu/lb the total heat gained by the R-134a.
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.(iii) What is the exit velocity of the steam?
