Concept explainers

Heat Exchangers

Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.

Heat Exchanger

The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.

A heat exchanger is being investigated as a waste heat recovery device. A heat exchanger is common device for using a hot fluid to heat a cold fluid without the fluids mixing. The following information is known. The cold fluid stream of liquid A enters at 294.2 K and leaves the device at a temperature of 320.91 K. Liquid A flows at a rate of 0.006 Kg/s and has a specific heat of 4180 J/(Kg K). Liquid B enters the device at a temperature of 350.2 K. Liquid B flows at a rate of 0.005 Kg/s and has a specific heat of 3900 J/(Kg K The dead state is at 293.2 K and 1 bar. The device is adiabatic and the pressure losses are neglected in this problem. Both liquids are incompressible materials. Tout=316.154K Answer the following: If the exiting liquid B is not used for any useful purpose, calculate the exergy destroyed associated with it.
Need answer ASAP In a counter-current-flow tubular heat exchanger, a liquid food (milk),flowing in the inner pipe, is heated from 20 to 40°C. In theouter pipe the heating medium (water) cools from 90 to50°C. The overall heat-transfer coefficient based on the insidediameter is 2000 W/(m^2-°C). The inside diameter is 5 cm andlength of the heat exchanger is 10 m. The average specific heatof water is 4.181 kJ/(kg-°C). Calculate the mass flow rate ofwater in the outer pipe. Compare the amount of milk being heated to concurrent design.

3.36 Both C's in a parallel-flow heat exchanger are equal to 156 W/K, U 327 W/m²K and A = 2 m². The hot fluid enters at 140°C and leaves at 90°C. The cold fluid enters at 40°C. If both C's are halved, what will be the exit temperature of the hot fluid?
A long, thin-walled double-pipe heat exchanger with tube and shell diameters of 0.01 m and 0.025 m, respectively, is used to condense refrigerant-134a with water at 20°C. The refrigerant flows through the tube, with a convection heat transfer coefficient of hi= 4100 W/m² °C. Water flows through the shell at a rate of 0.3 kg/s. The thermal resistance of the inner tube is negligible since the tube material is highly conductive and its thickness is negligible. Both the water and refrigerant-134a flows are fully developed. Properties of the water and refrigerant-134a are constant. Water properties: p = 998 kg/m³, v=u/p-1.004x 10-6 m²/s, k = 0.598 W/m. °C, Pr = 7.01 Cold water D Do
