This is a self-contained water circulating unit for studying the friction losses in pipes, pipe fittings, and valves; and to determine coefficients of discharge for primary flow measuring devices at various flow rates.
The unit consists of a pump, a storage tank and a water proof panel on which all friction loss components and the flow measuring devices are arranged.
Friction loss is measured by a pressure drop and coefficient of discharge is determined from a pressure drop and a flow rate. Flow rate is obtained from a water meter and a stop watch. The pressure drop is measured by differential pressure using manometer and differential pressure gauge. Pressure tapping is by small ball valves with quick connection. All pressure taps are connected by flexible hoses to a set of specially arranged manifolds such that differential pressure across any component can be measured simply by opening valves without removing the hoses. The unit is on a steel frame on wheels.
Instruction manual is also included.

- Friction losses in pipe fittings, valves, sudden expansion and contraction at various flow rates.
- Friction losses in primary flow measuring devices and comparison of coefficients of discharge at various flow rates.
