The heat transfer coefficient between a surface and a liquid is 57 W/(m2K). How many watts per square meter will be transferred in this system if the temperature difference is 10C?
If H is the work output of a heat engine and Q is the total heat input of an engine, then determine its thermal efficiency.
The efficiency of a thermal machine cannot have a value of 1 because a) There is no apparent reason, it is simply because of the way the calculation is made. b) it is impossible for a system to carry out a process in which the result is to use work to absorb heat from a source at low temperature c) it is impossible for a system to carry out a process in which the result is to absorb heat from a source at high temperature and convert it into work. d) it is impossible for a system to carry out a process in which it returns to the initial state and the result is to absorb heat from a source at high temperature and convert it entirely into work.

An exercise room has 6 weight-lifting machines that have no motors and 7 treadmills each equipped with a 2.5-hp (shaft output) motor. The motors operate at an average load factor of 0.7, at which their efficiency is 0.77. During peak evening hours, all 12 pieces of exercising equipment are used continuously, and there are also two people doing light exercises while waiting in line for one piece of the equipment. Assuming the average rate of heat dissipation from people in an exercise room is 600 W, determine the rate of heat gain of the exercise room from people and the equipment at peak load conditions.
1. A rigid tank contains a hot fluid that is cooled while being stirred by a paddle wheel. Initially, the internal energy of the fluid is 800 kJ. During the cooling process, the fluid loses 500 kJ of heat, and the paddle wheel does 100 kJ of work on the fluid. Determine the final internal energy of the fluid. Neglect the energy stored in the paddle wheel.
The interior of a refrigerator has a surface area of 6.2 m2 . It is insulated by a 2 cm thick material that has a thermal conductivity of 0.0199 J/m · s · ◦ C. The ratio of the heat extracted from the interior to the work done by the motor is 5.5 % of the theoretical maximum. The temperature of the room is 27.6 ◦C, and the temperature inside the refrigerator is 6.6 ◦C. Determine the power required to run the compressor. Answer in units of W.
The pump of a water distribution system is powered by a 15-kW electric motor whose efficiency is 90 percent. The water flow rate through the pump is 50 L/s. The diameters of the inlet and outlet pipes are the same, and the elevation difference across the pump is negligible. If the absolute pressures at the inlet and outlet of the pump are measured to be 100 kPa and 300 kPa, respectively, determine (a) the mechanical efficiency of the pump and (b) the temperature rise of water as it flows through the pump due to mechanical inefficiencies.
A mining company depleted more than half of its ore reserves and is no longer using all of its shaft infrastructure. It considers using one of the old shafts for pumped-storage hydro-electricity generation. This means that water will be pumped to the higher level, which is 1 000 m above the bottom level, at night when Eskom charges lower, off-peak, rates. The “higher level” will be changed into a dam (reservoir) by means of plugs that will be installed in some tunnels. The stored water has potential energy, which will be used to generate electricity for the mine at peak hours, when electricity is expensive. The pump that will be installed at the bottom of the column will also be used as a turbine for the generation of electricity The pump-as-turbine (PAT) must pump water to a height of 1 000 m through a column with an internal diameter (ID) of 345 mm. 3.1. Calculate the velocity of the water in the pipe if the quantity of water to be pumped is 220 litres per second (lps). 3.2.…
A differential thermocouple with sensors at the inlet and exit of a pump indicates that the temperature of water rises 0.048° F as it flows through the pump at a rate of 1.5 ft3/s. If the shaft power input to the pump is 23 hp and the heat loss to the surrounding air is negligible, determine the mechanical efficiency of the pump.
3. A classroom that normally contains 40 people is to be air-conditioned with window air-conditioning units of 5-kW cooling capacity. A person at rest may be assumed to dissipate heat at a rate of about 360 kJ/h. There are 10 light bulbs in the room, each with a rating of 100 W. The rate of heat transfer to the classroom through the walls and the windows is estimated to be 15,000 kJ/h. If the room air is to be maintained at a constant temperature of 210C, determine the number of window air-conditioning units required. draw a figure also, and explain each step by step solution.
