Pressure Under Water
Students can quantitatively see how pressure on an object changes as it moves deeper under a fluid with this interactive density pressure manometer activity. A hollow drum covered with a rubber membrane is connected to an open end manometer. When the drum is pushed under water the pressure on the rubber membrane increases the pressure inside the tubing, causing the manometer fluid level to change. The kit includes a tall vertical container, rubber drum, tubing open end manometer and demonstration guide.
To demonstrate Venturi effect. Made of glass with three side tubes for attaching an included three-leg manometer. The manometer is filled with colored water to show the relative pressures at significant points of the tube when gas is flowing through it. With Instructions. Without Clamp.
To Investigate the relationship between the speed of a fluid and its pressure. Consists of a glass Venturi tube with two different diameters. One pair holds a U-shaped tube in which a color liquid can be placed to demonstrate the different pressures exerted when air is blown through the tube. It includes two rubber tubes and glass Venturi tube fitted on stand.
Smoke cell is an apparatus used for the observation of Brownian motion in smoke particles. It comprises a box with plastic lid as well as flanges to be used with a microscope. The box consists of a smoke cell and a cylindrical condensing lens. Illumination is provided by a 12 volts 3 watt festoon bulb.Apparatus is pre-set to focus the light at correct height. The dimensions of the apparatus are 90 x 46 x 20 mm. The set is supplied with a squeeze bottle type smoke generator and user manual.
Surface Tension Balance, Searle’s
A horizontal frame is mounted on a rod fitted to a base & carries a steel wire stretched across it, the tension of which can be adjusted by a tightening screw. A light weight metal pointer with a counterpoise is attached to the centre of the wire by a clamp. A pan is hung from a notch in the pointer and has a hook at its underside from which can be suspended a light weight rectangular frame or a metal clip to hold a micro slide edge. The tip of the pointer moves over a graduated scale. With rectangular wire frame, slide clip, six micro slides and 3 meters of spare wire.
