The exhaust gases of a gas turbine, are used in a well insulated regenerator (heat exchanger) to raise steam at 2 bar, which is subsequently fed to a steam turbine in order to produce additional power. The air enters the regenerator at 758 K and exits at 350 K. The mass flow rate of the air is 3.2 kg/s. Water at 45°C and 2 bar enters the regenerator and exits as saturated steam at the same pressure. Determine: a) The mass flow rate of the water. b) The rate of entropy production in the regenerator in kJ/s.

Thermodynamics 2. Determine the useful power produced in a thermally insulated turbine from 30 bar and 360Ç to 0.5 bar and 90% quality. The water flow is 15000kg/h
1. The heat produced in a boiler is transferred from the combustion products to the water. While the temperature of the combustion products decreases from 1100 °C to 550 °C, the pressure remains constant at 0.1 MPa. The average specific heat at constant pressure of the combustion products is 1.09 kJ/kg.K. The water enters the system at 0.8 MPa and 150 °C, and leaves at 0.8 MPa and 250 °C. Determine the second law efficiency and the irreversibility for each kilogram of water vaporized for this process. Note: This is a thermodynamics course question. Please provide a solution that is clear and quick.

A Carnot refrigeration cycle is used as a reference to estimate the energy needed in an attempt to reduce the temperature of a laboratory sample to absolute zero. Suppose you want to remove 0.01 J of energy from the sample that is at 2x10-6K. If the high temperature is 20°C, the heat required is 982.05x10-5J. Analyzing these considerations, calculate the increase in laboratory entropy and the decrease in entropy in the sample.
A portion of a turbojet engine is shown in the figure below. Air flowing at 25 kg/s at 240 K and 80 kPa (State 1) enters an adiabatic and reversible diffuser with a velocity of 250 m/s. It leaves the diffuser with negligible velocity (State 2). As a result, you may assume the velocity of the air leaving the diffuser is small compared to the velocity of air entering the diffuser. The air is then compressed in an adiabatic compressor with an isentropic efficiency of 80%. The compressor requires 7 MW of power (work input). You may assume air is an ideal gas with constant specific heats. Use the correct specific heats in the table below in analyzing the different processes.

About 18% of the incoming mass flow exits a part of the turbine at a pressure of 5 bar, a temperature of 240°C and a velocity of 25 m/s.

A steady-state system for producing power consist of a pump, heat exchanger and a turbine. Water at 1.0 bar and 20°C (state 1) enters the adiabatic pump and leaves at 10 bar (state 2). The pump draws 110 kW of power, and the mass flow rate of water is 45 kg/s. The water leaving the pump enters a heat exchanger and heated at constant pressure to 400°C (state 3) using exhaust gases (Cp of gases = 1.1 kJ/kgK) that enters at 500°C and exits at 182°C. The steam is adiabatically expanded in a turbine having an isentropic efficiency of 0.71. The turbine exhausts (state 4) to the surroundings at 1.0 bar. What is thermal efficiency of this power production process? If the pump and turbine are reversible, would the efficiency of this system equal the maximum possible efficiency? (Answer Yes or NO and provide a short explanation.)

Air at 1 bar, 27 °C, with a volumetric flow rate of 40 m³/min enters the non-mixing counterflow heat exchanger part of an air-conditioning system. This air exits the heat exchanger at 0.95 bar and 17 °C. The cooling of this air is done by a stream of refrigerant R-134a that enters the heat exchanger at 5 bar with a quality of 0.3 and exits at 5 bar and 20 °C. Determine the overall rate of entropy production during this process, in kW. The overall heat exchanger is insulated. The operation is steady state, and the effects of potential and kinetic energy are negligible.
