Chapter 1, Problem 1.18P

A chiller is providing 5 tons of cooling to an air handler by cooling water transfer between the two devices. The chiller is drawing 3.5 kw of electrical power during this operation. At what rate must the chiller dump energy to the environment (say to a cooling tower) in Btu/hr to satisfy the first law of thermodynamics for that device? Notice that the cooling tower is rejecting not only the energy removed from the cooled space but also the energy input to the chiller.

A piston cylinder assembly contains steam. Initially, the specific internal energy (internal energy per unit mass) is equal to 2600 kJ/kg. The steam undergoes a process during which 90 kJ of heat is transferred to the steam. On the other hand, using a specific mechanism installed in the cylinder, 20 kJ of energy are transferred to the steam by work. If 10 kJ of heat is dissipated from the steam to the outside of the cylinder through the wall of the cylinder, Determine the work done by the steam on the piston. The specific internal energy at the final state is equal to 2500 kJ/kg. The mass of the steam is 4.4 kg. Select one: a. 1211 kJ b. 540 kJ c. 780 kJ d. 328 kJ
a 200-W vacuum cleaner is powered by an electric motor whose efficiency is 80%. (Note that the electric motor delivers 200 W of net mechanical power to the fan of the cleaners). Determine the rule at which this vacuum cleaner supplies energy to the room when running.
The Figure shows a solar collector panel embedded in a roof. The panel, which has a surface area of 24 ft2, receives energy from the sun at a rate of 200 Btu/h per ft2 of collector surface. Twenty-five percent of the incoming energy is lost to the surroundings. The remaining energy is used to heat domestic hot water from 90 to 120°F. The water passes through the solar collector with a negligible pressure drop. Neglecting kinetic and potential effects, determine at steady state how many gallons of water at 120°F the collector generates per hour.
