Hi
I'm trying to design a closed cycle hot water system for use with a Heat Exchanger with a Solar Collector, pump and tank. I want to be able to set the mass flow rate of the system but it seems that even though I've set the maximum flow rate in the pump, the actual flow rate is way higher than that. I'm guessing it is due to the tank. Can anyone help me out on what to do with the tank? I only want a simple tank with 1 inlet and 1 outlet and the mass flow rate to be the one i determine it to be.
