Consider again the pump and piping system of

Problem 10.61. Determine the volume flow rate and gate

valve loss coefficient for the case of two identical pumps

installed in series.

The resistance of a given pipe increases with age as

deposits form, increasing the roughness and reducing the

pipe diameter (see Fig. 8.14). Typical multipliers to be

applied to the friction factor are given in [15]
