1. The problem statement, all variables and given/known data Q3.1 (a) A pump forces 1m^3 /min of water horizontally from an open well to a closed tank where the pressure is 0.9 Mpa.compute the work the pump must do upon the water in an hour just to force the water into the tank against the pressure.sketch the system upon which the work iss done before and after the process. 2. Relevant equations 3. The attempt at a solution here flow rate is 1m^3/min p1=0.101325 pa p2=0.9 pa we don't know v. but equation formed will be as: w=dpdv now i'm where i can get v.
