TRAINING OBJECTIVES
• Measuring and testing the primary load losses that occur in a straight PVC pipe with an inner diameter 21.2 mm.
• Test of the relation between load losses and the fluid velocity in the pipe.
• Measuring the secondary load losses that occur in installation elements such as: elbows, tees, and valves, widening etc.

SECONDARY LOSS OF LOAD
This system is appropriate for the study of losses. It has straight sections of piping, for the study of primary loss generated therein.
It also has elements such as elbows of different diameters such as 90° and 45°, tees, widening, narrowing, various types of valves (ball, gate, membrane, non-return … ) with upstream and downstream pressure taps arranged for determining loss load between them produced with different flow rates.
All pressure connections have double sealed quick couplings.
The trainer has a differential manometer of water (1000mm) and a digital differential pressure gauge for measuring the resulting pressures.
