- Write a literature review of cooling tower : energy balance.Pls.answer thank you! 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/hr. There are 10 light bulbs in the room, each with a rating of 100 watts. The rate of heat transfer to the classroom through the walls and the windows is estimated to be 15,000 KJ/hr. If the room air is to be maintained at a constant temperature of 21°C, determine the number of window air-conditioning units required.(b) Bathroom sinks and some other fixtures include an overflow opening in the basin. This opening is located on the wall and near the top of the basin. The overflow opening serves two important functions: If the water tap is left on while the drain stopper is closed, the opening will channel water down into the drain opening rather than letting is spill out of the sink onto the floor. The overflow allows the sink to drain faster by introducing air into the system. A sink with a dimension given in Figure Q2(b), has water flows into it at a rate of 8 L/min. If the drain stopper is closed and water level in the sink remains constant, determine the average velocity of water flows through the 3.0 cm diameter overflow hole. Front 3 cm diameter overflow holes Q-8 L/min 15 3/4| 40 cm 15 cm Side (a) Figure Q2: (a) Picture of the sink; (b) Sink dimension (Ь)
