​This is a self-contained unit for studying the friction loss in pipes, pipe fittings and valves at various flow rates.

The unit consists of a pump, a storage tank and a water proof panel on which all friction loss components are arranged.

The loss 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.
