Hello - fundamental thermo question which is puzzling me...
It concerns a multiple effect evaporator with condenser. Hot vapour is water, cooling medium is water.
My question stems from the following:
When the flow of cooling water to the condenser is increased, the pressure in the condenser (and thus the pressure profile of the entire evaporator) is reduced.
Here's how I understand it...
How does this in turn lead to a reduction in evaporator pressure, please explain in basic terms (what's actually physically happening rather than just formulae! ).
Thanks in advance for any replies
Edit: Also the mass flow rate of condensate will be the same for a given flow "in" of water and steam. Some thermodynamic activity is occuring here I just cannot work out what!
