Stepwise and correct answer need. Chickens with an average mass of 1.6 kg and average specific heat of 3.54 kJ/kg*°C are to be cooled by chilled water that enters a continuous-flow-type immersion chiller at 0.5 °C and leaves at 2.5 °C. Chickens are dropped into the chiller at a uniform temperature of 15 °C at a rate of 700 chickens per hour and are cooled to an average temperature of 3 °C before they are taken out. The chiller gains heat from the surroundings at a rate of 400 kJ/h. Determine the rate of exergy destruction during the chilling process. Take T0=25 °C.

Under the conditions given below, design an water-cooling unit that cools 20000 kg of fruit and vegetables from 30 ° C to 5 ° C per hour. The cooling unit is in the water channel and the products cool as they pass through the water filled channel.

Thank you so much can you hand write clear please
One kg of steam at 1.4MP is throttled to IMPA at which pressure it is just dry. The steam is then expanded in an engine cylinder down to 0.1 MPa, the final dryness fraction being 0.75. The steam is finally passed to a feed water heater in which only the enthalpy of evaporation is extracted, the temperature of the feed water rising from 15 oC to 60 oC. Determine: a- the original dryness fraction of the steam b- the law of expansion in the engine cylinder c- the quantity of feed water heated/ kg of steam. 9. (0.994, 1.225; 8.98kg/kg steam)
