Energy Losses in Bends and Fittings

DESCRIPTION

When water flows through a pipe system, the flow resistances cause pressure losses to occur at pipe fittings and valves and fittings.

This unit can be used to investigate and visualize the pressure losses in pipe elements. The experimental unit can be used to assess how different pipe geometries affect the flow. Experimental unit comprises a pipe section containing several pipe elements with different flow resistances, as well as a contraction and enlargement piece. There is also a ball valve integrated in the pipe. There are pressure measuring points with annular chambers upstream and downstream of the pipe elements, which ensure accurate pressure measurement.

The pressure measuring points can be connected in pairs to a tube-manometers in order to determine the pressure loss of a pipe element.

The experimental unit is positioned easily and securely on the work surface of the Hydraulic bench base module. The water is supplied and the flow rate measured by Hydraulic bench. Alternatively, the experimental unit can be operated by the laboratory supply.

Specifications:
1. investigation of the pressure loss in flow through pipe fittings and in
the ball valve

2. sudden contraction and sudden enlargement, pipe bend, segment
bend, pipe angle and ball valve as measurement objects

3. annular chambers allow precise measurement of pressure
4. tube manometers for displaying the pressures
5. Bourdon tube pressure gauge for pressure measurement
6. flow rate determined by base module Hydraulic bench
7. water supply via Hydraulic bench or via laboratory supply
