Power professionals face problems in finding out flow and efficiency of fans and pumps quite frequently. They just have readings about current and inlet / out let pressure available with them. For helping them in such situations, I have created flow and afficiency calculators in excel in which just by entering available paremeters along with power factor, one gets resuls for flow and efficiencies of Pumps or fans instanly. I am giving below links to these utilities since attaching more than one link is not possible.
