Free Force Vortex Apparatus

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.

SPECIFICATIONS:

[1] Supply Tank – 0.4 X 0.3 X 0.5m height [2] Orifice – 8mm and 10 mm. [3] Mouthpiece (a) LID = 4 (b) L/D = 1 (c) Bordas mouthpiece. (d) Convergent mouthpiece. [4] X-Y gauge for orifice jet co-ordinates. [5] Measuring tank of suitable capacity OR a calibrated water flow meter. [6] Sump tank of suitable capacity. [7] 0.5 HP pump with valve. A technical manual accompanies the unit.

SERVICES REQUIRED:

[1] Flow surface 2 mtrs. X 1 mtr. X 1.5 mtrs. height. [2] 230 Volts, 5 Amp. Stabilized AC. Power Supply.

DESCRIPTION:-

The Lab setup consists of a channel having sufficient length and width in which water is supplied from the bottom. Required Notch is fitted at one end of this channel .A hook gauge with Vernier scale is fitted to measure the height of fluid in flow channel. Arrangement for fixing interchangeable notches is made. Set of three brass notches, i.e. rectangular notch. 60 V notch & 45 V notch provided along with the set up. 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 value are fitted in water line to conduct the experiment on different flow rate .Flow rate of water is measured with the help of measuring tank and stopwatch.

DESCRIPTION:-

The Set-up is designed to verify Reynold’s Apparatus experimentally. The Apparatus consists of a glass tube which one end having bell mouth entrance connected to a water tank. At the other end of the glass tube a cock is provided to vary the rate of flow. Flow rate of water can be measured with the help of Measuring Cylinder and Stop Watch, supplied with the set-up. A capillary tube is introduced centrally in the bell mouth. To this tube dye is fed from a small container, placed at the top of Constant head Tank, through polythene tubing.

EXPERIMENTS:-

Ø To study different types of flow. Ø To determine the Reynold’s Number and hence the type of floe either laminar or turbulent.

DESCRIPTION:-

A pontoon is allowed to float in a small tank having a transparent side. Removable steel strips placed in the model for the purpose of changing the weight of the model. Displacement of weight is measured with the help of a scale. By means of a pendulum (consisting of a weight suspended to a long pointer) the angle of tilt can be measured on a graduated arc. For tilting the ship model, a cross bar with two movable hangers is fixed on the model. Pendulum and graduated arc are suitably fixed at the center of the cross bar. A set of weights is supplied with the apparatus.

EXPERIMENTS:-

Ø Determination of the Metacentric height and position of the Metacentric height with angle of heel of ship model.
