The performance data of a water pump follow the curve fit H available = H 0
Question:
The performance data of a water pump follow the curve fit Havailable = H0 – aV̇2, where the pump’s shutoff head H0 = 7.46 m, coefficient a = 0.0453 m/(Lpm)2, the units of pump head H are meters, and the units of V̇ are liters per minute (Lpm). The pump is used to pump water from one large reservoir to another large reservoir at a higher elevation. The free surfaces of both reservoirs are exposed to atmospheric pressure. The system curve simplifies to Hrequired = (z2 – z1) + bV̇2, where elevation difference z2 – z1 = 3.52 m, and coefficient b = 0.0261 m/(Lpm)2. Calculate the operating point of the pump (V̇operating and Hoperating) in appropriate units (Lpm and meters, respectively).
