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 intended 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
manometers. Pressure tapping in by 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.
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.
