A 3 meter tall aluminum tank with a 7 meter diameter is completely filled with ethanol. The empty weight of the tank is 250 kg. If the ethanol starts at 25 deg C, and there is 3000 kJ of heat available for transfer, what final temperature can be reached? And, what percentage of the heat transferred does the ethanol and aluminum each account for? (ethanol density = .789 kg/L)

Problem 4. In order not to damage the resistance in the kettles, the difference between the temperature of the heater and the fluid should not exceed 25 °C. If the heat transfer area between the fluid and the heater is 78.5 cm² and the heat transfer coefficient is 400 W/m².K, find the maximum allowable power of the heater in order to boil water?
A stream of ammonia is cooled from 100oC to 20oC at a rate of 180 kg/hr in the tube side of a double-pipe counter-flow heat exchanger. Water enters the heat exchanger at 10oC at a rate of 250 kg/hr. The outside diameter of the inner tube is 3 cm and the length of the pipe is 7m. Using the log-mean temperature difference, calculate the overall heat transfer coefficient (U) for the heat exchanger. Determine the log-mean temperature difference. Determine the heat transfer coefficient for the heat exchanger. Cp for ammonia is 5234J/kgK and cp for water is 4180J/kgK.

Design a vapor compression cycle using ammonia as the refrigerant thatwill be used to maintain the temperature of a stream at -20°C. The condenser is air-cooled and the ambient temperature may be assumed to be 25°C. Assume a compressor efficiency of 80% and allow for 2°C of temperature difference between streams in the evaporator and condenser for practical heat transfer.

10.5-2. Minimum Gas Rate and Height of Water-Cooling Tower. It is planned to cool water from 110°F to 85°F in a packed countercurrent water-cooling tower using entering air at 85°F with a wet bulb temperature of 75°F. The water flow is 2000 lb/h ft² and the air flow is 1400 lb air/h ft2. The overall mass-transfer coefficient is KG a = 6.90 lb mol/h · ſt³ · atm. (a) Calculate the minimum air rate that can be used. (b) Calculate the tower height needed if the air flow of 1400 lb air/h ft² is used. .
