Piping Loss Apparatus
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.
TYPICAL EXPERIMENTS
- Friction losses in straight pipes at various flow rates.
- 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.

Hydraulic Studies and AccessoriesPipe Friction
This equipment measures pressure drop when water flows through a vertical pipe at various flow rates both laminar and turbulent. It is to be used with Hydraulics Bench i.e. HB100 or HB100N (separately supplied).
It consists of adjustable constant head water source of removable clear acrylic cylinder for laminar flow. Turbulent flow may be achieved by directly connecting the pipe to the Hydraulics Bench water supply. A water manometer with a vent valve, a hand air pump and a differential pressure gauge are provided for measurement of pressure drop. A valve at the outlet is used to control outlet pressure.
TYPICAL EXPERIMENTS- Investigations of laminar and turbulent flows
- Demonstration and measurement in a change of the laws of resistance (friction factor) from laminar to turbulent flow
