During open-heart surgery, a patient’s blood is cooled down to 250C from 370C using a concentric tube counter-flow heat exchanger. Water enters the heat exchanger at 40C and leaves at 180C. Blood flow rate during the surgery is 5 L/minute.
Use the following fluid properties:

Effectiveness of the heat exchanger is _________ (round off to 2 decimal places).
    Correct answer is '0.4242'. Can you explain this answer?

    Inlet temperature of hot fluid (Thi) = 370C
    Outlet temperature of hot fluid (Th

    ) = 250C
    Inlet temperature of cold fluid (TCi) = 40C
    Outlet temperature of cold fluid (TCe) = 180C
    Effectiveness (∈)



    Hence, the correct answer is 0.4242.
