In order to determine the optimal

size of the piping, compare the total

cost of the equipment's operation

(cost

the

pump,

equipment,

piping

and

consumption). By increasing the

discharge diameter reasonably, it

reduces the required BHP due to the

low friction. Perform di erent tests

using several piping diameters until

you nd the more convenient.

The pipe, valves, etc. should be

new expansive joints to protect the

must be primed (suction pipe and

pump's body should have liquid),
