Separating Throttling Calorimeter
AIM
To find out dryness fraction of steam by combined separating and throttling calorimeter.
PRODUCT DETAILS
The steam passing out from separating calorimeter may still contain some water vapour , in it . in other words it may not be absolutely dry . again , in a throttling calorimeter steam after passing through the throttle valve must be superheated or at least dry saturated . this limits the extent of dryness fraction that can be reliably measured , depend up on the pressure of steam in the main steam pipe . if a sample of steam, which may be still wet after passing through the throttle valve i.e it will not be superheated . thus under this condition the throttling calorimeter fails to enable us in determining the value of dryness fraction of steam . to overcome this difficulties we make use of separating and throttling calorimeter . first the steam is passed through separating calorimeter where itlosses most of it’s moisture and becomes comparatively drier, it is than passed through the throttling calorimeter where super heating takes place with out changr of total heat . the temperature and pressure of steam after throttling are measured by using a thermometer and manometer respectively.DESCRIPTION
The set up consist of a separating and throttling calorimeter . a steam generator is provided at the base of the apparatus . a thermostat knob is provided at the front of apparatus to control the temperature inside the steam generator . steam from steam generator is passed from separating calorimeter where most of the water partical get separated from steam and then passed to throttling calorimeter where steam get superheated . after that superheated steam passed through heat exchanger to condense the steam.SAPARATING CALORIMETER
It consist of two concentric chamber , the inner chamber ,and the outer chamber . which communicates with each other through an opening at the top. As the steam discharge through the metal baskets ,which has a large number of holes , the water partical due to there heavier momentum get separated from the steam and collected in the chamber. The comparatively dry steam in the inner chamber moves up and than down aging through the annular space between the two chambers and enters the throttling calorimeter .THROTTLING CALORIMETER
It consist a narrow throat . pressure and temperature are measured by manometer and thermometer . the steam after throttling process passed through the heat exchanger and condensate is collected .UTILITIES REQURIED

Flow Over Weir Or Open Channel Apparatus
Flow Over Weir Or Open Channel Apparatus:
A ‘WEIR’ is the name given to concrete or masonry structure built across a river (or stream) in order to raise the level of water on the upstream side and to allow the excess water to flow over its entire length to the downstream side. Weirs may also be used for measuring the rate of flow of water in river or streams.
Different shapes of “WEIRS” generally used are sharp-crested weir, broadcasted weir and ogee shaped weir.
In the unit a centrifugal pump sucks the water from the sump tank, and discharges it to a small flow channel. The weir is fitted at the end of channel. All the weirs are interchangeable. The water-flowing over the weir falls in the collector. Water coming at from the collector can be directed to the sump or can be directed in to the measuring tank for measurement of flow.
SPECIFICATIONS:
[1] The unit is provided with following weirs: (a) Sharp-crested weir. (b) Broad-crested weir. (c) Ogee shaped weir. [2] Pump 1/2 H.P. monoblock. [3] Flow measurement – Measuring tank calibrated water flow meter is used. A technical manual accompanies the unit.SERVICES REQUIRED:

Laser Reflection and Refraction Tank
Description
Laser Reflection and Refraction Tank demonstrates the principle of reflection and refraction. The clear circular acrylic tank has a circular scale graduated on the white base of the tank, making it easy to measure angles. Adjust the pivot-arm mounted laser to any angle along its full 360° range and measure the angle of reflection or refraction. Rotate the laser and observe first a reflected ray, then both a reflected and refracted ray, and finally just a refracted ray. Leveling screws on the tank’s base make leveling quick and easy. The laser is attached to the pivot-arm by a magnet and can be removed for use in other experiments. Instructions included.

SILICON RUBBER CORK
PRODUCT DESCRIPTION
A Bung, Stopper or Cork is a truncated cylindrical or conical closure to seal a container such as bottle, tube or barrel. Unlike a lid, which encloses a container from outside without displacing the inner volume, a bung is partially inserted inside the container to act as a seal. These can be used for all types of glass bottles. These stoppers fit tightly to prevent chemical leaks. We are one of the very few manufacturers of silicone rubber corks, septa gasket, silicone rubber stoppers in India.
Features:
- Silicon rubber cork / stopper /bung,
- Silicon rubber cork for filtration flask.

Optical Disc
Description
A 500 mm diameter disc marked every 5° is mounted on a heavy stand and is rotatable around its centre. It can be held in any desired position. The lamp house, with a 12V 24 W special filament lamp has rotatable slots to provide light beams of varying widths and also narrow single, double and triple beams. Attached to the lamp house is an adjustable lens carrier with lens to provide diverging, parallel or converging light beams which are clearly visible in classroom. The lamp house can be held in any desired position around the disc. Optical elements are two 50 x 25 mm plane glass mirrors, and a metallic cylindrical mirror, each mounted in a holder, for reflection. For refraction, 20 mm thick acrylic semi-circular block, bi-convex lens, bi-concave lens each 140 mm long and a trapezium with 125 mm base are provided. Each of these elements has embedded magnets to hold on to the disc.XTEMOS ELEMENT
