Pumping power calculation for jet impingment flows
 
Hi everyone,

I am working on jet impingement cooling of heat sources. I found Avg Nu for all heat sources and now i want to calculate pumping power (= velocity * Pressure drop) to find optimum performance (high Nu and low pumping power). But i found negative pressure at the inlet (Because high pressure at stagnation point). Please help me out in calculation of pressure drop.

Thanks in advance.
