Condenser a steam power plant that operates on a simple ideal ranking cycle and has a net power output of 22MW. Steam enters the turbine at 7Mpa and 450.05°C and is cooled in the condenser at a pressure of 10kpa by running cooling water from a lake through the tubes of the condenser at rate of 1750 kg/s. Determine the mess flow rates of steam through the steam turbine assuming that the cp of superheated steam is 2.9593kJ/kg.K.
A 540,000 kJ/h capacity refrigeration system using Refrigerant 22 and served by a single compressor unit operates at an evaporator temperature of -23 oC and a condensing saturation temperature 40oC. To get rid of the single compressor load, a modification is proposed to use two stage of compression with refrigerant intercooling. (a) Determine the power required in the original system. (b) Determind the power required for the proposed modified system.
1. A refrigerant system using refrigerant 22 is to have a refrigerating capacity of 60 kW. The evaporating temperature is -10°C and the condensing temperature is 42°C. Determine the: • Enthalpy at each point of the cycle in kJ/kg • Refrigerating Effect in kJ/kg Compressor work in kJ/kg • Energy rejected in kJ/kg • Mass flow rate of refrigerant in kg/s • Compressor power in kW • Heat rejected in kW • Coefficient of Performance Note: Draw the P-h Diagram with labels. Show your system balancing for checking.

Refrigerator 1 simulates an ideal refrigerator and therefore operates on a Carnot cycle using R-134a as the refrigerant at a flow rate of 1.4 kg/sec. The condensing and evaporating temperatures are 30 °C and -10 °C, respectively. To assess the performance of Refrigerator 1, you must submit the report. of the project with the following information: Enthalpies corresponding to the states indicated in the cycle (1, 2, 3 and 4); 1.a. The cooling rate (QL); 1.b. The work provided to the fluid by the compressor; 1.c. The work generated by the turbine; 1.d. The condenser heat rejection rate (QH); 1e. The coefficient of performance of the cycle;
Question 3 In a vapour-compression refrigeration system, refrigerant - 134a enters the compressor superheated at 200 kPa and - 5 °C. The refrigerant enters the condenser at 1.4 MPa and 75 °C, and exits at 1.4 MPa as a saturated liquid. There is no significant heat transfer between the compressor and its surroundings, and the refrigerant passes through the evaporator with a negligible change in pressure. If the refrigerating capacity is 105 kW, represent the cycle on a T-s diagram and determine: a) the mass flow rate of the refrigerant in kg/s, b) the power input to the compressor in kW, c) the coefficient of performance, and (2) d) the isentropic compressor efficiency
Considering now the real case, where the turbine and feed pump are not isentropic, and the feed pump electric motor and the electric generator are not 100% efficient, Determine for unit mass flow rate of refrigerant circulated, the quantities (I) to (VI) as listed above, briefly contrasting the values calculated here and those calculated,
