A house is kept at 22^oC in the winter by means of electric heaters. On a cold day, the heaters are on for 18 hours and use an average power of 5 kW.

a. How much power would be saved if a heat pump with a COP of 2.0 was to be used instead?

b. Assuming the cold spell lasts a month (30 days), how much money would be saved by using the heat pumps instead of the heaters? Use $0.15/kWh.

The dry air mass flow rate entering the mixing chamber : Hot, moist outside air passes over a cooling coil, from which it exits in a saturated state at p=14.7lbf/in^2 and T=65F. The air is then mixed adiabatically with room air at p=14.7lbf/in^2, T=75F, phi=25%.

For a control volume enclosing the heat exchanger : Saturated water vapor at 100 kPa enters a counter flow heat exchanger operating at steady state and exits at 20C with a negligible change in pressure. Ambient air at 275 K, 1 atm enters in a separate stream and exits at 290 K, 1 atm.

Relative humidity passes over the cold evaporator coil : Air at 1 atm 30 C and 80% relative humidity passes over the cold evaporator coil of an air conditioner at constant pressure. The air and condensate leave the coil at 18C. The moist air flow rate is 0.02 kg/s.

The dry air mass flow rate and water vapor mass flow rate : At a certain location in a duct, moist air at 35 C, 125 kPa and a relative humidity of 50% flows at a volume flow rate of 50 m^3/s. using tabular data, determine the following: i)the humidity ratio ii)the dry air mass flow rate (kg/s) iii) the water ..

Design the svaj curves for the follower using polynomials : Equally spaced parts, with the distance between the parts being 10 inches, are coming on a conveyor belt. A machine tool has to operate on the part for 1 second as the part is moving on the conveyor. The speed of the conveyor belt is 5 in/second.

Reversible power cycle operating between hot-cold reservoirs : The thermal efficiency of a reversible power cycle operating between hot and cold reservoirs is 20%. Evaluate the coefficient of performance of a reversible refrigeration cycle operating between the same two reservoirs.

Find the speed of the particle if it is a proton : A charged particle travels unelected through perpendicular electric and magnetic fields whose magnitudes are 4000N/C and 40mT, respectively. Find the speed of the particle if it is a proton

Efficiency is used to pump water through a schedule : A 20 hp pump with 80% efficiency is used to pump water through a Schedule 40 3-inch pipe made of commercial steel. The pipe outlet is at a gage pressure of 100 psi, and is 350 feet above the inlet, which is at ambient pressure. The total pipe length ..
