Suitable for use with linear air track. With a flexible hose terminating in a tapered adapter.230 V a.c., 50 Hz.

To demonstrate that speed of flow increases and pressure decreases in a constricted section. A 500 mm long tube with 10 mm bore is constricted near its center. Short side tubes are provided in all three sections to which manometer tubes can be jointed with rubber tubes, complete with three manometer tubes.

Comprises a circular gauge on a pillar fitted on a heavy base, with a tubule to provide connection to the pressure system.

Simple, a glass J tube mounted on a wooden stand with scale 0-80 cm. Its closed limb is 400 x 1 mm bore & the open limb approx. 780 x 8 mm bore. A loose fitting glass plunger is pushed into the open limb & by displacement the height of mercury can be adjusted from about -50 mm to +450 mm relative to closed end. Requires about 6 ml of mercury. Supplied without mercury.

Two glass tubes 220 mm long, one with closed top & the other open and connected by 1 metre pressure rubber tubing, are mounted on two brackets sliding on two vertical metal rods fixed rigidly on a stand. The stand has a graduated scale 0 to 100 cm. Supplied without mercury.

Wide bore glass tube closed at top is mounted on a scale 0 to 600 mm with zero corresponding to the inside of the top end. Air is trapped by coloured oil in a metal pressure chamber fitted with a Bourdon Gauge and a riffled inlet tube with stop cock. With a plastic safety screen over the tube.

To demonstrate Archimedes principle, all brass, bucket with suspension loop at top and a hook at bottom, with the cylinder having a suspension hook at top. Cylinder is 50 x 16 mm diam., overall length including hook and suspension loop is 110 mm approx.

Metal frame with six glass tubes of different bores, each of 150 mm length, fitted with corks, to show different heights of water column in different bore tubes.

Pack of 100

To demonstrate transmission of pressure by liquids.

Mains operated electronic timer reads 0 to 99.99 seconds. The display comprises of four 7 segment digits to read seconds and centiseconds. Two pairs of colour coded 4 mm
sockets with two push buttons are controlled with a mode switch which enables either make or break pulse to be used to operate the timer. With re-set action.

To demonstrate the principle of conversion of momentum and to show that momentum has direction as well as magnitude. Consists of a curved wooden runway 280 x 67 mm length x height with an 8 mm groove, an index mark near top and a slotted metal plate at bottom. A device can be attached to the plate to provide support to the object sphere either exactly opposite the runway or at slightly oblique position. A plumb bob and 2 steel balls are provided. The apparatus can be fixed to the table with a GClamp (which is not provided).

A metal bar 1000x19x6 mm with holes at every 50 mm along the centre line. A steel knife edge is mounted in a wall bracket for suspension of the bar.

Stainless steel rod 1200 mm long, l0 mm diam. with one pair each of small & large, light & heavy masses, two steel knife edges in adjustable holders & a metal bracket support drilled for wall mounting.
