Water is pumped between two reservoirs in a pipeline with the following characteristics:
D = 300 mm, L = 70 m, ƒ = 0.025, ΣK = 2.5.
The radial flow pump characteristic curve is approximated by the formula:
Hp = 22.9 + 10.7Q - 111Q2
1. Determine the system's characteristic equation in terms of Q when Z2 -Z1 = 15 m (Hs)
2. Determine discharge Q, and head, H.
3. If the pump is to be run at 4495 rpm with the Q and H in part (2), can you tell what type of pump you have?
4. What impeller diameter size would you recommend for this pump?
5. What is the horsepower (bhp) required to run the pump?
