Study Of Pipe Fitting

DESCRIPTION:

An orifice is an opening made in the side or bottom of tank, having a closed perimeter, through which the fluid may be discharged. A mouthpiece is short tube fitted to a same size circular opening provided in a tank so that fluid may be discharged through it. Orifice and mouthpiece are used to measure the rate of flow of liquid. The apparatus is designed to measure the co-efficient of discharge of orifice & mouthpiece. The apparatus consists of a supply tank, at the side of which a universal fixture for mounting orifice or mouthpiece is attached. A centrifugal pump supplied the water to supply tank. Head over the orifice/mouthpiece is controlled by a by pass valve provided at pump discharge. A measuring tank is provided to measure the discharge. A gauge for measuring X and Y co-ordinates of jet from the orifice is provided, which is used to calculate Cv of orifice.

DESCRIPTION:-

A Pitot tube is used to measure the local velocity at a given point in the flow stress. A Pitot tube of standard design made of copper / SS is supplied and is fixed below Vernier scale. The Vernier scale is capable to measure the position of Pitot tube in transparent pipe section. The pipe has a flow control valve to regulate the flow. A U-tube manometer is provided to determine the velocity head. Present Set-up is self-contained water re-circulating unit, provided with a sump tank and a centrifugal pump etc. Flow control valve and by-pass valve are fitted in water line to conduct the experiment on different flow rates. Flow rate of water is measured with the help of measuring tank and stop watch.

EXPERIMENTS:-

Ø To find the point velocity at the center of a tube for different flow rates of water and calibrate the Pitot tube Ø To plot velocity profile across the cross section of pipe

DESCRIPTION:-

The experimental set up consist of a circular transparent cylindrical tank in which four circumferential jets have been placed along the circumference of the cylinder near its bottom which helps in the formation of free vortex. It is assumed that the torque exerted by these jets is negligible. The Orifice is reducing bush so that a reduced diameter can be investigated. The plate can also be rotated with the help of a variable speed motor so that the cylinder rotates about its vertical Axis with the help of a V belt and forced vortex is formed. Conditions wear allowed to steady state and the depth of flow at any particular point was observed not to change over a period of time. The experimental procedure involves measurement of resulting free surface that represents the variation of the sum of the pressure and datum head.

SCOPE OF EXPERIMENTS:-

Ø To plot the surface profile of a free and forced vortex by measurement of the surface profile coordinates and to show that total energy is constant throughout vortex.

DESCRIPTION:-

The apparatus consists of two pipelines emerging out from a common manifold. One pipeline contain a Venturimeter, second contains an Orifice. The pressure tapings from the Venturimeter and Orificemeter are taken to differential manometer to measure pressure difference. The Venturimeter and Orificemeter are connected in parallel and anyone of them can be put in operation by operating valves provided at the downstream. These valves can also regulate the flow. Present Set-up is self contained water re-circulating unit, provided with a sump tank and a centrifugal pump. Flow control valve and by-pass valve are fitted in water line to conduct the experiment on different floe rate. Flow rate of water is measured with the help of measured with the help of measuring tank and stop watch.
