    How to calculate the mass flow rate ?



    Hello all, I don't know if it's the right place to post this but forgive me if it's not.

    I need to calculate the mass flow rate of a glycol circulated around a mold Project 2.jpg

    The load in the solidification cell is 92000 Joule, I want to get it to -15C in about 30 Minutes so I think I will need to get the inlet temperature of glycol to -20C.


    what I am thinking about is that:

    Capacity=Load/Time=92000/(30*60)=52 Watt

    Capacity=M.*Cp*(Tout-Tin)

    If that is true then I have two unknowns mass flow rate and the output temperature then how to calculate the mass flow rate to get the right pump?

    Correct me if I am wrong.

    You could calculate it emperically. Tune the flow until you detect an outlet temperature of -15. Only possible of course if you have a practical setup.
