How many Btu/h would be produced in a 12-kW electricheater?
In a refrigeration cycle, the refrigerant gains heat in the evaporator and in thesuction line. In a certain refrigeration system, R-134a gains 67.8 Britishthermal units per pound (Btu/lb) in the evaporator. It then gains 2.5 Btu/lb inthe suction line. Find in Btu/lb the total heat gained by the R-134a.
2) The energy consumed by a shower for 30 days is 22kwh. It is known that the resistance of the showerhead is 20 ohms and that its nominal current is 15A. So, what is the time in minutes that the shower was turned on during this period?
The heat engine, in which the working gas is air, performs a circular change. First, air at a temperature of 20 °C is isobarically expanded to temperature of 50 °C. After that, it's isochorically cooled back to the initial temperature and then finally compressed isothermally to the initial volume. What is the machine's efficiency?
Room (A) contains only an air conditioner with 6 KW capacity that works 3 hours per dayRoom (B) contains only a refrigerator with 0.9 KW that works 20 hours per day .which of the two rooms would get higher electricity bill by the end of day
A refrigerator is used to keep the cold space at 5 °C by rejecting 8 kJ/s of heat by the condenser tothe outdoor air at 25 °C. If the compressor consumes 3 kJ/s of power, determinei. the rate of heat removed from the cold space (kJ/s),ii. the COP of the refrigeratoriii. the minimum power input to the compressor for the same rate of heat removed (kJ/s), andiv. draw the schematic of the refrigerator as a reversed heat engine.
Subject : Thermofluid A well-sealed house left alone during the midday heat was found to be at 35oC. He turns on the air conditioner, which cools the entire house to 24oC in 30 min. If the COP of the air-conditioning system is 2.6, determine the power drawn by the air conditioner. An estimated of 750 kg of air is within the house for which cv = 0.72 kJ/kg·oC and cp = 1.0 kJ/kg·oC.
A heat pump is used to extract heat from the outside atmosphere to heat the inside of a building. On a day when the outside air temperature is Tc°C, the heat pump is operating to a COP of 3.7, maintaining the inside temperature of the building at Th°C. If the building is losing heat at the rate of 53,709 kJ/hour in these conditions, determine how much power (kW) must be supplied to a heat pump? Keep two decimal places
The steam from a boiler enters a steam turbine and work is done by the steam turbine. After work done, the steam is condensed by condenser.

1. A gas undergoes isobaric process with a constant pressure of 2000 Pa. If the heat of 800 J is added to the process, the volume expands from 0.120 m to 0.200 m. What is the change in its internal energy? 2. An engine absorbs 500 J of heat and reject 100 J of heat to cold reservoir in each cycle. What is its efficiency? 3. From Question 2, how much work does the engine do in three cycles? 4. A refrigerator has a coefficient of performance of 2.0. In each cycle it absorbs 3.4x10 J of heat from the cold reservoir. During each cycle, how much heat is released to the high-temperature reservoir? 5. During running, you lost 4.0x10 J of heat, and your internal energy also decreased by 1.6x10* J. How much work did you do in the match?
A heat pump used for heating shown is essentially an air conditioner installed backward. It extracts energy from colder air outside and deposits it in a warmer room. Suppose the ratio of the actual energy entering the room to the work done by the device’s motor is 10.0% of the theoretical maximum ratio. Determine the energy entering the room per joule of work done by the motor given that the inside temperature is 20.0°C and the outside temperature is -5.00°C.
