The refrigeration effect produced by a system is 10 TR and work done by the low-pressure compressor, and high-pressure compressor is 3 and 4 kW respectively. What is the value of C.O.P. for the given conditions? Correct Answer 5

GiveR.E. = 10 TR = 10 x 3.5 = 35 kW Low-pressure compressor work, WL = 3 kW High-pressure compressor work, WH = 4 kW C.O.P. = R.E. / Total Work = R.E. / WL + WH = 35 / (3 + 4) = 35 / 7 = 5.

Consider the following statements in respect of a vapour-absorption refrigeration cycle: 1. The absorption refrigeration cycle is generally used when waste heat is a available from an existing source or when free energy like solar energy is to be used. 2. There are no moving parts in the absorption refrigeration plant except a small liquid pump. 3 the value of the coefficient of performance is nearly the same in both vapour-absorption and vapour-compression refrigeration plants. Which of the above statements are correct?

Given below are two quantities named 1 and 2. Based on the given information, you have to determine the relationship between the two quantities. You should use the given data and your knowledge of Mathematics to choose between the possible answers. Quantity 1: P and Q can do a work in 6 days and Q and R can do a work in 60/7 days and P and R can do a work in 20/3 days. If Q and R work for first 2 days and left the work. Find the total time taken by P to complete the remaining work. Quantity 2: A and B can do a work in 8/3 days, B and C can do the same work in 3 days and A and C can do the same work in 24/5 days. In what time C alone can complete the work?
Work done by A in one day is 2 times of the work done by B in one day. Work done by B is 3 times of the work done by C. If C can alone complete the work in 35 days, In how many days can A, B, and C together complete the work?
Work done by A in one day is half of the work done by B in one day. Work done by B is half of the work done by C in one day. If C alone can complete the work in 7 days, in how many days can A, B and C together complete the work ?
