Communicating Vessel   (MC-1198)

Apparatus as per illustration, made of glass with four different shape &.size limbs mounted on wooden stand.

Lift Pump Mounted   (MC-1199)

A working model of a clear glass to show and explain the principle involved. It has a cylinder of 25 mm dia and overall lengths of 350 mm. Cylinder is provided with non-return float valves and outlet is by means of a side tube. Glass part mounted on wooden stand.

Lift Pump Unmounted   (MC-1200)

Same as above but without stand.

Force Pump Mounted   (MC-1201)

A working model to demonstrate the principles involved in the action of a force-pump. Cylinder is 25 x 350 mm dia x overall height. It is provided with a non-return float valve at its lower end. Lower part of the cylinder has an outlet side tube communicating with the lower end of another cylinder also equipped with non-return valve. Outlet tube from the secondary cylinder is drawn out into a jet to demonstrate ability of force pump to eject water at high pressure. Mounted on wooden stand.

Force Pump Unmounted   (MC-1202)

Same as above but without wooden stand.

Hydraulic Press (Bramah Press) Mounted   (MC-1203)

The apparatus comprises a pumping cylinder dia 25mm x 350mm overall height, provided with a piston and a non return valve at its lower end. A side tube joined at lower end of cylinder is also provided with a non return valve as shown in the picture.

Hydraulic Press (Bramah Press) Unmounted   (MC-1204)

Same as above but without wooden stand.

Hydraulic Press   (MC-1205)

It has two graduated syringes mounted on a metal frame, having capacities of 20cm3 and 5cm3 respectively with ground pistons. Both the syringes are connected through a 3 position tap. These syringes may be exposed to atmosphere through this tap, isolated or interconnected as desired. Both the pistons are provided with platforms for loading. This item is used for demonstrating how fluid pressure is transmitted and mechanical advantage can be achieved.

Hydraulic Press   (MC-1206)

Comprises two heavy walled transparent plastic or Glass cylinders 40 mm and 15 mm I.D. approximately. Both fitted with non-return valves and pistons. Pump work by hand lever 315 mm long, ratio about 2:1, safety valve provided in the larger piston so that pressure in excess of that can safely be applied to the cylinder enables the water to rise above the piston and escape through the overflow pipe at the top. Stop cock at base of small cylinder for replenishing cylinders with water by rubbers tubing. Removable loading platform. Apparatus is mounted on base board.

Fluid Pressure Apparatus   (MC-1207)

To demonstrate the transmissibility of fluid pressure. The apparatus comprises two metal cylinders 15 mm and 30 mm dia respectively fitted with piston and connected by a tube. The pistons are provided with rods terminating in plate forms for loading with masses required. The complete apparatus is fitted on a wooden base.

Pressure Syringe Glass   (MC-1208)

To show that pressure of a liquid is transmitted equally in all directions A glass cylinder approximately 200 x 25 mm provided with plunger terminating in a spherical bulb 50 mm diameter, the spherical bulb having a series of a small holes along its circumference.

Same as above, but made of Plastic   (MC-1209)

Same as above, but made of Metal   (MC-1210)

Pressure Syringe Glass   (MC-1211)

To demonstrate that liquid transmit pressure equally in all directions. Comprises a glass bulb with long neck which acts as a cylinder for the piston. Complete with pressure gauges which can be attached at different points on the bulb by rubber corks.

Cartesian Diver   (MC-1212)

It is to demonstrate the transmission of pressure by a liquid. Approx 35 mm long (hollow figure made of glass with one fine opening, to float upright in water filled glass cylinder). When the diver is placed in a glass jar full of water it floats. When a stopper or membrane is fitted on top of cylinder, changing the pressure within the Jar, the diver will sink or rise depending on the pressure applied. Supplied without cylinder.
