n a heat exchanger, a fluid with a density of 2.5 m per hour and a specific heat of 0.727 kcal / kg ° C cools from 120 ° C to 40 ° C and heats 10 m per hour with an inlet temperature of 10 ° C. Since the total heat transfer coefficient is 1000 kcal / m h ° C, (Psu-1000 kg / m²; Cpsu = 1 kcal / kg ° C) a) Parallel flow case, b) Counter flow case, calculate the surface area of the pipe.

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.
Question
In a heat exchanger, a fluid with a density of 2.5 m per hour and a specific heat of 0.727 kcal / kg ° C cools from 120 ° C to 40 ° C and heats 10 m per hour with an inlet temperature of 10 ° C. Since the total heat transfer coefficient is 1000 kcal / m h ° C, (Psu-1000 kg / m²; Cpsu = 1 kcal / kg ° C) a) Parallel flow case, b) Counter flow case, calculate the surface area of the pipe.
