QUESTION 02
2.1
A pipeline connects two reservoirs such that the total head between them, when
water is being pumped from one to the other can be expressed as H= 25 + (77,46Q)²
where H is the total head (m) and Q is the discharge in m³/sec. The characteristic
curve of the particular pump that can be used, is tabulated as follows:
