December 28, 2013, 01:16	Pumping power calculation for jet impingment flows	#1
prasanthkumar New Member Prasanth Kumar Join Date: Dec 2013 Posts: 1 Rep Power: 0	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.
