This apparatus is used to measure Darcy’s friction coefficient (F) for given pipes.

The system is closed circuit.

The apparatus consists of:

• A Centrifugal Monoblock Pump 1/2 HP Motor (ISI Kirloskar Make)
• S.S. Sump Tank 50 Ltr. to collect the water.
• S.S. Measuring Tank 30 Ltr fitted with piezometer tube to measure the discharge. Damper is used to collect the water in S.S. MEASURING TANK for certain time.
• Pipe & ISI mark Control Valve and regulating valves are used to circulate water.
• Bye-pass line is also used to regulate the discharge.
• This apparatus consists of a three G.I. pipe 15mm & 20mm. The pressure tapings are provided 70 cm apart on each pipe. Each taping is connected to the mercury U Tube Manometer to measure head difference.
• Hand shuts valves are provided on each pipe to open supply in the pipe. Powder coated paint – the tanks are well painted to increase their life.

Experimental capabilities:

• To determine the loss coefficient for different type of fittings.
• Comparison of pressure across two different types.
