<p class="MsoNormal"><span style="color:#1F497D">I would also like to simulate the drain-back of a flat plate collector but I do not know how to do it. So far, I simulated the FPC using the type 1b but now I do not know how can I simulate the drain-back, because
if the inlet flow rate of the collector is zero kg/h also the outlet flow rate will be zero. I think that I should change the type 1 for another one, but I do not know which is the type that I should use, could you give me a clue, please?<o:p></o:p></span></p>
