A vegetable freezing plant requires 35 tons of refrigeration. The freezing temperature is – 38°C while the ambient temperature is 25°C. If the performance of the plant is 30% of the theoretical reversed Carnot cycle working within the same temperature limits, calculate the power required (given: 1 ton of refrigeration = 210 kJ/min).

A5 kg block of fe is dropped into a very large vat of water. the fe and water initial temperatures are 95 and 25 c, respectively. the fe final temperature is 25 c and the water can be treated as a thermal reservoir,. treated as a thermal reservoir take the water to be the system and determine the entropy generation. report vour answer in kj/k.
