FLUID FRICTION

Description

FLUID FRICTION

This unit is used to study fluid friction losses through pipes with valve diameters and orifice meters. The pipe to be tested can be selected through the valve system without interruption. Energy loss measurement is done by measuring differential pressure and measurement of mercury pressure.

Learning :
• Study of regular pressure losses
• Piping of different diameters (DN15, DN25)
• Smooth or rough piping of the same diameter (DN15)
• Study of singular pressure losses
• Bernoulli’s Theorem
• Study of a transparent venturi
• Study of a transparent orifice plate flowmeter

Specifications :
• The trainer is installed on an aluminum profile structure fitted with four directional castors with brakes.
• Translucent PVC piping, diaphragm flow control valve, circuit pressurizing valve, 21 pressure taps with self-closing connector
• Smooth pipe DN25 length 1.5m
• Smooth pipe DN15 length 1.5m
