AspenHX-Net input issue
Thread Content
In the input information for hot and cold streams in Aspen HX-Net, there is a parameter called MCp (heat capacity flow rate). There is one MCp value for each stream state – should this value represent the initial state or the final state? I would appreciate it if experts could provide some guidance. And is Enthalpy the ΔH before and after the logistics state that we often talk about? Thank you first, little Xie!
I have the same doubt too.:lol Please, experts, come and answer the question
I think I understand now; MCp is actually a constant value. It took me so long to figure out what was being discussed regarding heat capacity and flow rate, but I’m impressed with myself – it’s simply ΔH divided by ΔT. That enthalpy value represents the ΔH before and after the change in the state of the fluid, as we commonly refer to it. What a long time it took!
This is the heat capacity flow rate, which has no relation to the initial and final states
