![Engr 321 Thermodynamics, Web 2 and Web 3 Spring 2018 Homework 8 Due: Wednesday Apnil 25t (Extension: Friday April 27 1. The water boiller of a Rankine cycle power plant runs at 3.0 MPa. The highest and lowest temperatures of the plant are 400°C and 60°C, respectively. Find the plant efficiency and the efficiency of a Carnot cycle opatng with the same temperatures. 2. The plant from the previous question has a major problem. The quality at the turbine outlet is too low, and that could damage the turbine blades. It is proposed to reheat the turbine outlet at 800 kPa to then feed into a low-pressure turbine (see Figure 9.9 of 8h edition 9.7 f h edition). What should be the reheat (superheated temperature] to make sure the turbine quality stays at 92%. 3. A refrigerator like the one in Figure 9.23 from your textbook uses R-134a as working fluid. The minimum temperature is -10 C and the maximum pressure Is 1 MPa. Find the high temperature specific heat transfer, low temperature specific heat transfer and the COP.](http://img.homeworklib.com/questions/1ba6f100-ba5d-11eb-aa51-5fe045f7660a.png?x-oss-process=image/resize,w_560)

Consider a steam power plant that operates on a reheat Rankine cycle and has a net power output of 80 MW. Steam enters the high-pressure turbine at 10 MPa and 500°C and the low-pressure turbine at 1 MPa and 500°C. Steam leaves the condenser as a saturated liquid at a pressure of 10 kPa. The isentropic efficiency of the turbine is 74 percent and that of the pump is 95 percent. Determine the quality (or temperature, if superheated) of the...

Combined cycle power plants are common because of their high efficiency and scalability. They typically combine a gas turbine cycle (the Brayton Cycle) with a steam turbine cycle (the Rankine Cycle) [1]. The goal of this project is to determine the operating efficiency and profitability of a realistic combined cycle power plant. The power plant is as follows: 1. A natural gas-fired Brayton cycle with mÛ air,Br = 1.25 kg s−1 . (a) Ambient air at 1 bar and 300...
