Question

Pipe Diameter(D)=150mm, Pipe Length(L)=980m, Friction factor(lambda)=0.05, Water level(h)=18m

(i) Neglecting minor losses plot the pipeline characteristic curve (system curve), for a flow rate range of 10-60 m3 /hr.

(ii) For an average flow of 20 m3 /hr select a suitable pump from the pump performance charts provided.

(iii) What are the discharge and head values you would record at duty point for the selected pump?

Answer 1

ANSWER:--

HEADLOSS :-- Head loss refers to the measurement of energy dissipated in a system due to friction. It accounts for the totality of energy losses due to the length of a pipe and those due to the function of fittings, valves and other system structures.
