A pump operating at 1750 rpm operates in a closed system. The system has 185 ft head loss at 200 gpm. The pump has a shutoff head of H = 132 ft, and produces 123 ft head at 100 gpm. (a) (5 pt) Develop the equation for the pump curve. Approximate the curve as a quadratic as was done for the homework. (b) (5 pt) Develop the equation for the system curve. (c) (10 pt) What will be the flow rate and head loss in the system for the pump operating at 1750 rpm? (d) (10 pt) If the pump has a variable frequency drive, what must the rotational speed be for the system to have 250 gpm flow rate? What will be the head loss at the new flow rate?
