Pls. Answer thank you! An air-conditioning system is used to maintain a house at 65°F when the temperature outside is 85°F. The house is gaining heat through the walls and windows at a rate of 1250 Btu/min, and the heat generation rate within the house from people, lights, and appliances amounts to 350 Btu/min. Determine the minimum power input required for this air-conditioning system

In an absorption refrigerator, the energy driving the process is sllPplied not as work, but as heat from a gas flame. (Such refrigerators commonly use propane as fuel, and are used in locations where electricity is unavailable. *) Let us define the following symbols, all taken to be positive by definition: Qf = heat input from flame Qe = heat extracted from inside refrigerator Qr = waste heat expelled to room Tf = temperature of flame Te temperature inside refrigerator Tr = room temperature Use the second law of thermodynamics to derive an upper limit on the COP, in terms of the temperatures Tf, Te, and Tr alone.

Oven Temperature 0 wwwwww Valve ↑y Steam B Piston Oil Supply H Working Cylinder Fig. Q3 Fig. Q3 shows an arrangement for controlling the temperature of a steam heated oven. utilizing temperature sensitive bellows and a hydraulic servomechanism. An increase in oven temperature causes the bellows to expand and the left end of the 'walking beam' ABC to move downwards. thus activating the hydraulic mechanism. The end C of the walking beam actuates a valve to reduce or increase the steam flow into the oven depending on the temperature in the oven. When .x is zero the beam ABC whose mid-point is B, is horizontal. Given that, (a) oil flow in the servomechanism per unit displacement (b) area of cross section of the piston in the working cylinder -Q = A (c) heat transfer across the walls of bellows to the thermos- sensitive fluid in the bellows =q=H(0-1) where I' is the temperature of the fluid inside the bellows and H is a constant.
