Fluid Mechanics: Pressure Loss in Bends & Fittings MODEL FM 05
Fluid Mechanics: Pressure Loss in Bends & Fittings MODEL FM 05
Sci-tech Pressure Loss in Bends and Fittings Apparatus Model FM05 is important equipment for any Fluid Mechanics and Hydraulics Engineering Laboratory of an educational institution.
Item Description
Study of pressure losses in bends and fittings in any pipe system is useful in view of the loss of head and consequent pumping power requirements. The Pressure Loss in Bends and Fittings apparatus has been designed to enable students to measure pressure losses across various types of bends and fittings in a typical pipe system.
The apparatus, including the instrumentation for pressure measurements, is mounted in a robust vertical frame work mounted on wheels. The study devices include bends of small and large radius, 450 mitre bend, 900 elbow, sudden enlargement and contraction and a gate valve. All these devices are equipped with pressure tapings both in the upstream and the downstream to measure the pressure drop. Pressure tapings across bends and fittings are connected to a multi-tube water manometer mounted on the frame work.
A hand pump with a non-return valve is used to pressurize manometers. Pressure tapings across the gate valve is connected to the Bourdon tube pressure gauge. Another gate valve is provided at the downstream of the apparatus to vary the water flow rate through the devices. The FM00 Hydraulic Bench or any other standard hydraulic bench models can be used to supply water.
