Problem 2.069 SI A window-mounted room air conditioner removes energy by heat transfer from a room and rejects energy by heat transfer to the outside air. For steady-state operation, the air conditioner cycle requires a power input of 0.7 kW and has a coefficient of performance of 5.5. Determine the rate that energy is removed from the room air, in kw. If electricity is valued at $0.1/kW·h, determine the cost of operation for 24 hours of operation. ▼ Part A...

Lab 14 Electricity Bill Worksheet Background knowledge. The power of an electrical appliance is measured in watt (W). One watt is a measure of the energy used up in one second. The unit used for calculating power consumption is the kilowatt-hour (kWh). In order to calculate power consumed by an electrical appliance, we first convert the power to kilowatt (kW). For example, 800 W=0.8 kW, 2000 W = 2.0 kW and so on. One unit...
