- A heat exchanger is to be designed to condense 8 kg/sec of an organic liquid (tsat=80°C, hfg=600 KJ/kg) with cooling water available at 15°C and at a flow rate of 60 kg/sec. The overall heat transfer coefficient is 480 W/m2 -°C calculate: a) The number of tubes required. The tubes are to be of 25 mm outer diameter, 2 mm thickness and 4.85 m length b) The number of tube passes. The velocity of the cooling water is not to exceed 2 m/sec.An air-cooled condenser has an h value of 30 W/m2-K based on the air-side area. The air-side heat transfer area is 190 m2 with air entering at 27°C and leaving at 40°C. If the condensing temperature is constant at 49°C, what is the air mass flow rate in kg/s? Let Cp(air) = 1.006 kJ/kg-K. Draw and label the temperature-flow diagram. Round off your answer to three (3) decimal places.The condenser of a room air conditioner is designedto reject heat at a rate of 15,000 kJ/h from refrigerant-134aas the refrigerant is condensed at a temperature of 408C. Air(cp 5 1005 J/kg?K) flows across the finned condenser coils,entering at 258C and leaving at 358C. If the overall heat transfer coefficient based on the refrigerant side is 150 W/m2?K,determine the heat transfer area on the refrigerant side.
- G A double-pipe heat exchanger will be used to cool a hot stream (in inner pipe, ID 2.067 in, OD= 2.375 in) from 350°F to 250°F by heating a cold stream (in annulus, ID 4.05 in) from 80°F to 120°F. If the heat-transfer coefficients are hi = 200 and ho=350 Btu/h. ft² °F, calculate the wall temperature of inner pipe. =How would you formulate this problem to obtain a more meaningful result which desired to cool a gas has [Cp = 0.35 Btu/(Ib)(°F)] from 190 to 95°F, using cooling water at 83°F. Water costs $0.30/1100 f, and the annual fixed charges for the exchanger are $0.60/ft of inside surface, with a diameter of 0.0775 ft. The heat transfer coefficient is U = 8 Btu/(h)(f)(F) for a gas rate of 2900 Ib/hr. Plot the annual cost of cooling water and fixed charges for the exchanger as a function of the outlet water temperature. What is the minimum total cost?A heat exchanger is heating water on the tube side with steam condensing on the shell side. The water is entering at 45 0 F and exiting at 175 0 F. No instruments are available for measuring the tube side water flow but condensed steam from the shell side is being collected at a rate of 43 GPM. If the tube area of the exchanger is 350 Ft2 , and the overall heat transfer coefficient clean was 900 BTU/Hr.Ft2 F0, how much has the overall heat transfer coefficient changed, if at all? Note: Latent heat for water/steam at 212 0 F is 970 BTU per pound of water. A gallon of water weighs 8.34 lbs.
