HF135A PIPING LOSS APPARATUS, Large
GENERAL DESCRIPTION

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.
