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?
In a laboratory test run, the rate of drying was found to be 0.5 × 10-3 kg/m2.s, when the moisture content reduced from 0.4 to 0.1 on dry basis. The critical moisture content of the material is 0.08 on a dry basis. A tray dryer is used to dry 100 kg (dry basis) of the same material under identical conditions. The surface area of the material is 0.04 m2/kg of dry solid. The time required (in seconds) to reduce the moisture content of the solids from 0.3 to 0.2 (dry basis) is

In the question below, a statement is given which is followed by three assumptions numbered I, II and III. An assumption is something that is supposed or taken for granted. You have to consider the following assumptions and decide which of the assumptions is implicit in the statement. Statement: After more than two weeks, all 12 boys and their coach, stuck in the flooded Tham Luang Cave have been rescued by the Thai navy seal team. The last three members of the 'Wild boar' football team and their coach were rescued today ending a three-day rescue attempt that had caught the world's attention. Assumptions: I. The ‘Wild Boars' soccer team and their coach got trapped when they set out to explore the vast cave complex after soccer practice when a rainy season downpour flooded the tunnels. II. Four more of the boys were carried on stretchers out of the labyrinthine Tham Luang cave on the Myanmar border at dusk on Monday, bringing to eight the number brought out after two rescue pushes on successive days. III. The rescuers have been learning from experience and were two hours faster in bringing the second batch of survivors out on Monday.

What is the Evaporator economy of the 1st effect if we evaporate 10kg/hr of water from a feed of 50kg/hr at a temperature of 25oC to a final temperature of 100oC in an hour in a triple effect forward feed evaporator which has steam supply of 25kg/hr? Given the concentration changes from a value of 0.3 to 0.55 in the 1st effect of the setup. Latent heat of vaporization of water = 2,260 kJ/kg Specific heat capacity = 6 KJ/Kg K
