This is a comprehensive 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.
All friction loss components and the flow measuring devices are arranged on a water proof panel which is attached to a floor standing steel frame. The apparatus is to be used with a Hydraulic Bench (separately supplied) or an outside water supply.
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 in 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 with adjustable footings.
Instruction manual is also included.
