Answer. c) Determine the total heat transfer coefficient. d) Calculate the efficiency of the heat
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.
For a 50 m2 tubular heat exchanger operating under the following conditions:
| Heat Capacity C, kW/K | Inlet Temperatures °C | Output Temperatures °C | |
| Hot Fluid | 6 | 70 | X |
| Cold Fluid | 3 | 30 | 60 |
a) Calculate the exit temperature of the hot fluid.
b) Does the heat exchanger operate in reverse flow or parallel flow or is this not determined from the available information? Answer.
c) Determine the total heat transfer coefficient.
d) Calculate the efficiency of the heat exchanger.
e) What would be the effectiveness of this heat exchanger if its length had been greatly increased? Answer.
