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 14179

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

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.
