Water enters a heat exchanger operating stably at P = 10 bar and T = 80oC, given that the outlet is saturated steam at P = 10 bar a. Use the steam table to find the process-specific enthalpy variation b. Using the approximation = 4.19 for liquid water, find the change in enthalpy when heated from T = 80oC to the boiling point at P = 10 bar c. Compare the results of a and b, why is there a difference between these two results.
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.
Water enters a heat exchanger operating stably at P = 10 bar and T = 80oC, given that the outlet is saturated steam at P = 10 bar
a. Use the steam table to find the process-specific enthalpy variation
b. Using the approximation = 4.19 for liquid water, find the change in enthalpy when heated from T = 80oC to the boiling point at P = 10 bar
c. Compare the results of a and b, why is there a difference between these two results.
