Efficiency of Ejector "as pump" I was asked to find the efficiency of a steam ejector experiment "as a pump". So I tried the formula : [(m(P/density + V^2/2))discharge - (m(P/density + V^2/2))suction]/ (m(P/density + V^2/2))steam inlet. I am getting an efficiency of 0.5%. Is this a reasonable result or am I approaching this wrong? Thanks!
