What is the main difference between a copper and a cupronickel coaxial heat exchanger, and where is each used?
A heat exchanger is heating water from 50 0 F to 160 0 F using steam on the shell at atmospheric pressure condensing at 212 0 F. If the overall U is 710 BTU/(hr 0 F ft2) and the exchange rate is 9,000,000 BTU/hr, what tube area is needed?
Which conditions will you select, parallel flow or counter flow heat exchangers..?
In a countercurrent double-pipe heat exchanger, the hot oil entering the inner tube at 420 K with a flow rate of 60 g/s is required to be cooled to 320 K. In the space between the outer tube and the inner tube of the heat exchanger, cooling water flows at the same linear speed as the oil. Cooling water enters the heat exchanger at 290 K. The inner tube inner diameter of the heat exchanger is 25 mm and the outer tube inner diameter is 40 mm. Calculate the length of the heat exchanger. The oil side heat transfer coefficient is 1.6 kW/m2 K, and the water side heat transfer coefficient is 3.6 kW/m2 K. The densities of oil and water can be taken as 0.8 and 1.0 g/cm3, respectively, and the specific heats of oil and water can be taken as 2.0 and 4.2 kJ/kg K, respectively. Wall effects can be neglected. Flow cross-sectional area = (PI)*D2 /4 F2
What type of heat exchanger is a waste heat boiler? Is it a regenerator or a recuperator? Choose only between the two.
Consider a water-to-water double-pipe heat exchanger whose flow arrangement is not known. The temperature measurements indicate that the cold water enters at 20°C and leaves at 50°C, while the hot water enters at 80°C and leaves at 45°C. Do you think this is a parallel-flow or counter-flow heat exchanger? Explain.
Concentric Tube Heat Exchanger For equivalent inlet conditions, why should a counterflow heat exchanger have better effectiveness than a parallel unit?
Consider two double-pipe counter-flow heat exchangers that are identical except that one is twice as long as the other one. Which heat exchanger is more likely to have a higher effectiveness?
As shown below, water at a rate of 45,000 (forty five thousand) kg/h is heated from 80°C to 150°C in a two-shell and eight-pass tube heat exchanger with a total surface area of 925 m². The value of the correction factor for the cross flow heat exchanger is 0.97. The hot flue gas has thermophysical properties such as air entering at 350°C and exiting at 175°C. Determine the overall heat transfer coefficient.
For specified inlet and outlet temperatures, for what kind of heat exchanger will the DTlm be greatest: double- pipe parallel-flow, double-pipe counter-flow, cross-flow, or multipass shell-and-tube heat exchanger?
Cold water (cp 5 4180 J/kg?K) enters the tubes of aheat exchanger with 2-shell passes and 20-tube passes at 208Cat a rate of 3 kg/s, while hot oil (cp 5 2200 J/kg?K) enters theshell at 1308C at the same mass flow rate and leaves at 608C.If the overall heat transfer coefficient based on the outer surface of the tube is 220 W/m2?K, determine (a) the rate of heattransfer and (b) the heat transfer surface area on the outer sideof the tube.
To cool the lubricating oil, a concentric counter-flow heat exchanger is utilized, with the water flowing via an internal pipe with an internal diameter of 0.02 m and a flow rate of 0.18 kg/s. The intake and output oil temperatures are 95ºC and 65ºC, respectively, as the oil runs through the outer annulus (0.04 m) at a flow rate of 0.12 kg/s. The water enters the heat exchanger at a temperature of 30ºC. Stating all the necessary assumptions, (a) determine required length of the pipe. (b) Considering the effect of fouling during operation through time and the heat transfer resistance would be affected, discuss the design and operation considerations to minimize the fouling problem on the opertion of the heat exchanger during design and operation stages. Consider average value of Engine oil property: Cp=2131 J/kgoC; μ=0.0325 Ns/m2; K=0.138 W/moC Consider average value of water properties: Cp=4174 J/kgoC; μ=725x 10-6 Ns/m2; K=0.138 W/moC; Pr=4.85 Please clear Answer words
