A liquid flowing through a pipe will experience energy losses due to viscous resistance. The system is closed circuit. This apparatus is used to measure the losses due to:

• Sudden Enlargement
• Sudden Contraction

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:

• Large bend made up of G.I.
• Sudden enlargement from 20mm dia to 25mm dia.
• Sudden contraction from 25mm dia to 20mm.
• 20mm Bend
• ISI make gate valve of 25mm dia. U-tube manometer is connected to pet cock through plastic tubing to measure head difference.
• 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 drops across two different types.
