Pipe Friction Apparatus

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

 A Centrifugal pump of 25mm x 25mm with 1/2 HP Motor
 M.S. SUMP TANK 80 X 33 X 30cm to collect the water.
 M.S. MEASURING TANK 45 X 30 X 30cm fitted with Piezometer tube o measure the discharge. Damper is used to collect the water in M.S. MEASURING TANK for certain time.
 G.I. pipe of internal dia 25.4mm (1") and Gunmetal 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 ½”, 3/4", 1". The pressure tapings are provided 90cm apart on each pipe. Each tapings are 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.

The tanks are well epoxy painted inside to prevent rust hence increase the life of tank.

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