STUDY OF FLOW NETWORKS: Influence of flow velocity on pressure loss.

Features- pressure losses in the piping system,- pressure measurement without interaction via annular chambers,- transparent measuring objects for determining flow rate. Learning objectives/experiments,- pressure losses in pipes, piping elements and fittings,- how the flow velocity affects the pressure loss,- determining resistance coefficients,-opening characteristics of angle seat valve and gate valve,-familiarisation with various measuring objects for determining flow rate:,-- Venturi nozzle,-- orifice plate flow meter and measuring nozzle.

Specification:

• investigation of pressure losses in piping elements and shut-off devices

• different measuring objects for determining flow rate according to the differential pressure method

• six pipe sections capable of being individually shut off, with different piping elements: sudden contraction, sudden enlargement, Y-pieces, T-pieces, corners and bends

• one pipe section to hold interchangeable shut-off/measuring objects

• measuring objects made of transparent material: Venturi nozzle, orifice plate flow meter and measuring nozzle

• shut-off devices: angle seat valve, gate valve

• annular chambers allow measurement of pressure without interaction

• 2 twin tube manometers for measuring the pressure difference

• flow rate determined by base module

• water supply using base module or via laboratory supply. Technical data: Pipe section to hold fittings or measuring objects- 20x1,5mm, PVC.
