The Liquid Sedimentation Apparatus is designed to study the settling characteristics and particle sizes of suspended solid. The rear panel is translucent with back lighting. Scales are provided on the tubes. Sedimentation rate is observed using a stopwatch. The tubes can be removed for washing, filling or mixing of solid particles. Five transparent glass sediment tubes are mounted vertically on a rigid frame.
Experiments:
Settling rate curve.
Effect of suspension height on sedimentation rates.
Effect of concentration on sedimentation rate.
Effect of particle size distribution.
Effect of flocculent.

Supplied complete with adjustable safety valve, pressure guage, air cock, drain off syphon and inner liner. Also supplied, 10 robust autoclave milk sample bottles and screw caps, 250ml capacity, and 55 metres of autoclave tape.
The cylindrical boiler is filled with a known quantity of water, then heat is given through the resistance. Heat is supplied to the water in the boiler under steady-volume rather than steady-pressure conditions. The Computerized Marcet Boiler is designed to determine the corresponding temperature and pressure values for wet saturated steam at all pressures ranging from atmospheric up to 17 bar. The liquid gradual evaporation will thus cause pressure - and therefore the saturation temperature - to increase in the boiler enclosed space and the values are visualized on digital indicators. Moreover, the transducers and the dedicated software allow the data acquisition of the main thermodynamics quantities and to obtain as a table or as a graph, the acquired values and the thermodynamic calculated quantities.

The friction disks are pushed together, and force transmission comes about as aresult of the friction. The slip can be varied with the help of anelectronically controlled throttle valve. It replaces the known viscous clutch in four-wheel drive. As soon as a difference in speedcomes about between the front and the rear axle, the swash plate turns in the housing. Fluid is pressed to the disk plunger by hydraulic pistons.
