An autoclave contains 1000 cans of pea soup. It is heated to an overall temperature of 100C. If the cans are to be cooled to 40C before leaving the autoclave, how much cooling water is required if it enters at 15C and leaves at 35C? The specific heats of the pea soup and the can metal are 4.1 kJ/kgC and 0.5 kJ/kgC, respectively. The weight of each can is 60g and it contains 0.45 kg of pea soup. Assume that the heat content of the autoclave walls above 40C is 1.6x104 kJ and that there is no heat loss through the walls. Ans. 1,526.85 Kg

An autoclave contains 1000 cans of pea soup. It is heated to an overall temperature of 100 °C. If the cans are to be cooled to 40C before leaving the autoclave, how much cooling water is required if it enters at 15°C and leaves at 35°C? The specific heats of the pea soup and the can metal are 4.1 kJ/kg°C and 0.5 kJ/kg°C, respectively. The weight of each can is60g and it contains 0.45 kg of pea soup. Assume that the heat content of the autoclave walls above 40°C is 1.6x104 kJ and that there is no heat loss through the walls. Answer must be 1,526.85 Kg

5. The two tanks (Tank A and Tank B) are connected by a valved tube. Initially, the valve is closed. Tank A contains 1 MPa, 1.5 kg of water vapor at 350°C, and tank B contains 3 kg of saturated water at 150°C and dryness x=0.5. The valve was opened and the water vapor moved and finally the pressure in the two tanks was equal to 300 kPa. Answer the following questions. (1) Calculate the volumes of tank A and tank B, respectively. (2) Calculate the final temperature and dryness (in case of saturation). (3) Find the amount of heat transfer during this process.
