MS-172 PVG FLUID PRESSURE APPARATUS

To demonstrate that the pressure in a liquid is transmitted equally in all directions. The apparatus consists of a glass cylinder approximately 250 x 25 mm. diameter provided with a plunger and terminating in a spherical bulb 50 mm. diameter. The bulb has a series of nine small holes around its circumference. The apparatus is filled with water and the plunger firmly depressed. Water is ejected from all holes with equal force.

MS-175 PVG WORCESTER CIRCUIT BOARD

Demonstrates force from atmospheric pressure. When evacuated, a considerable force is required to separate these hemispheres. Consists of two heavy gauge, aluminium hemispheres about 10 cm. in diameter with O-ring seals and exhaust valve which fits 1/4” diameter pressure tubing. Supplied without stand and vacuum pump.

MS-176 PVG MAGDEBURG HEMISPHERES

To demonstrate that in the absence of atmospheric pull, bodies of different masses and density fall through a given distance in the same time. Comprises a borosilicate glass tube of size 600 x 25 mm, fitted with rubber bung at both the ends, one solid and other with a hole to carry a brass tube and 6 mm diameter rubber tubing for connection to a vacuum pump. A Hoffman clipis used on pressure rubber tubing. Inside the tube is a guinea generally a small coin and a feather. In air, the guinea and the feather fall at different speeds due to air resistance. To show this, turn the tube upside down so both items fall from one end of the tube to the other. The guinea will fall much faster than the feather because it is affected less by air resistance. (The feather has a greater surface area which comes in contact with the surrounding air). Turn the vacuum pump on and expel as much air from the tube as is safely possible. When you have done this, tighten the Hoffman clip and turn off the pump. Inside the tube you should now have a near vacuum. Turn the tube upside down once again and you will see that the guinea and feather arrive at the other end at the same time. With no air in the tube, both objects fall at the same speed as there is no air present (therefore no or negligible resistance) to affect their descent.

MS-18 PVG INCLINOMETER

This apparatus is for demonstration the volume of air enclosed in the column. Comprises a vertical glass tube of wide bore mounted on side of scale graduated 0- 60 cm. fitted on wooden base having plastic feet. This glass tube is connected to cylinder metal reservoir by a pressure tubing and stopcock. Reservoir is connected to dual2 2 scale pressure gauze reading 0 - 4.2 kg/cm and 0 - 60 lb/in above and side to a riffled inlet with stopcock for connection to foot pump. As the pressure in the oil reservoir increases, colored oil is forced into the glass tube and volume of the contained air and its actual (total) pressure are noticed. Size of base 235 x 145 mm. Overall height of apparatus 750 mm. Supplied without oil.
