Ammonia refrigerant circulates in a refrigeration system with one compressor serving two evaporators where one evaporator carries a load of 35 kW at 10°C and the other a load of 70 kW at -5°C. A back pressure valve reduces the pressure in the 10°C evaporator to that of the -5°C evaporator. The condensing temperature is 37°C. Calculate the mass of the refrigerant in kg/s.

QUESTION 8 It is proposed to have carbon dioxide (CO2) gas pass through an uninsulated nozzle. The CO2 is to enter at 319 K, 387 kPa, at a velocity of 7 m/s. The CO₂ is to exit the nozzle at 341 K, 105 kPa, and a velocity of 118 m/s. The mass flow rate of the CO2 is 0.21 kg/s. The nozzle surface is maintained at 390 K. The rate of entropy generation for the proposed process is kW..... to 4 d.p. Use cold-air standard analysis and Take R= 0.1889 kJ/kgK and Cp=0.846 kJ/kgK Provide unit symbol.

A boiler produces 5.4 tonnes/hour of steam at a pressure of 1.5 MPa and a temperature of 350°C. Feedwater enters at a temperature of 44.5°C. At exit from the economizer part of the boiler the temperature is 93.5°C. At exit from the evaporator part of the boiler the steam is 90 A % dry. Energy is supplied by 600 kg of coal per hour, which has a calorific value of 32 MJ/kg. The A/F ratio is 15 1. The temperature of the flue gas at exit from the the economizer part of the boiler is 210°C. The average specific heat at constant pressure of the in the economizer is 1045 J/kg.K.
