DI/ A two-stage vapor compression cycle with 15 TR (refrigeration capacity) using ammonia as a refigerant is carried out with water and flash inter-cooling and water sub-cooling as shown in figure 1 The operating pressure of the condenser is 12 bars, and the evaporator is 3 bars, while the flash tank operating pressure is 6 bars. The limiting temperature for inter-cooling and sub-cooling is 20 °C. Draw the cycle on p-H diagram showing all points, and then find the power...

5. Because of the high specific heat capacity of water compared to that of soil, a large lake takes longer to heat in the summer than an equivalent area of land. This effect moderates the temperature along the lakeside. But how does the cooler lake keep lakeside communities cooler, i.e. what is the mechanism of energy transfer? (0.5 mark)
In a physics lab students are conducting an experiment to learn about the heat capacity of different materials. The first group is instructed to add 1.5-g lead pellets at a temperature of 92°C to 125 g of water at 16°C. A second group is given the same number of 1.5-g pellets as the first group, but these are now aluminum pellets. Assume that no heat is lost to or gained from the surroundings for either group. (a) If the final...
