For use as a water turbine to drive a generator producing electricity or for use as a pump driven by a motor and raising a head of water to produce potential energy.
The rotor has eight 'bucket' blades and is housed in a block turbine chamber with a clear Perspex front.
Two inlet tubules (for turbine and pump operation respectively) and one outlet tubule are provided and the shaft carries a 15 mm.
diameter pulley.
With driving belt.
To show conversion of mechanical energy into electrical energy.
Turbine with transparent cover, inlet and outlet tubes, directly connected to a dynamo. Fitted on base.
This model uses the same basic assembly as the motor, but is mounted on a baseplate 230 x 90 mm approx.
which also carries a hand-drive pulley 120mm.
diameter coupled to the smaller dynamo pulley by a rubber belt to give a step-up ration.
Electrical output is via a pair of 4mm sockets.
The model may also be used as a motor on a 6-8 V D.C. supply.
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.
To show the forces which can be exerted during thermal expansion or contraction.
Comprising a heavy cast iron frame 340x120x100mm with slotted end pillars to carry a stout iron bar.
The bar is threaded at one end for a large tensioning nut and has holes at the other end to accommodate the cast iron breaking bars.
Supplied complete with ten breaking bars.
For use with motor/generator to give an indication of their output when used as dynamos.
The lamp-holders are connected in parallel.
Supplied with three lamps 3.5 V 0.25 A, M.E.S.
