Different Impellers of Pumps and Turbines

Description

For showing potential energy in a wound-up spring and its conversion to electrical energy by driving a dynamo and lighting a lamp. May also be used to wind up a weight on a cord showing the change from potential energy to kinetic and back to potential in the raised weight. The steel shaft carries a clock spring with a free wheel device and winding ratchet, also an aluminium 'V' pulley 56 mm. diameter. One end of the shaft overhangs the base for use as line shaft when winding up a weight. Dimensions 220 x 100 x 100 mm. high Supplied complete with driving belt.

Description

Determination of charge on a electron by measuring a known distance on the basis of number of times of fall under gravity and of rise in uniform vertical electrostatic field in a series of charged oil drops.

Description

Highly useful for demonstrating the most fundamental and frequently used mechanism. Very useful for engineering students. All the components are made of high degree of precision. These modules are assembled on transparent perspex sheets to facilitate teaching. Easy to assemble or disassemble.
