A heat pump is used to heat water by extracting heat from ambient air. This system is turned to be used to cool a room by extracting heat from the air and reject it to water. The heat pump has a COP of 3.1 (as a heating system). The room receives heat energy from outside at 45, 000 kJ/h. The work done by the compressor is 6.2 kW. The system uses an ideal - vapour compression cycle. a) Draw the schematic of the set-up clearing labelling the components and the relevant energy exchanges. b) What is the rate of heat rejection? Is this enough to meet the cooling requirements and maintain a constant temperature.

In a steam boiler, hot gases from a fire transfer heat to water which vapourizes at constant temperature.In certain case, the gases are cooled from 1100°C to 550°C while the water evaporates at 220°C. Thespecific heat of gases is 1.005 kJ/kg K, and the latent heat of water at 220°C is 1858.5 kJ/kg. All the heattransferred from the gases goes to the water. How much does the total entropy of the combined system ofgas and water increase as a result of irreversible heat transfer ? Obtain the result on the basis of 1 kg ofwater evaporated. If the temperature of the surroundings is 30°C find the increase in unavailable energydue to irreversible heat transfer.

Liquid isobutane can be used as a heating fuel. Now, there is an isobutane tank that initially contains 15 L of liquid isobutane, at an ambient temperature of 25 ° C. If a leak occurs in the tank connection tube, determine the temperature of the isobutane when the pressure in the tank drops to 1atm. Also determine the total amount of heat transfer from the environment to the tank required to evaporate all the isobutane in the tank

A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. The cylinder has a piston that moves in or out, as necessary, to keep a constant pressure on the mixture of 1 atm. The cylinder is also submerged in a large insulated water bath. (See sketch at right.) The temperature of the water bath is monitored, and it is determined from this data that 266. kJ of heat flows out of the system during the reaction.
