Air+Water Turbine Models (With Water-Recycling System) - Thames & Kosmos AIR Plus Water Power Experiment Manual

Air+Water Turbine Models
AIR+WATER TURBINE
The first seven models in this kit use an enclosed water turbine to drive their gears and wheels.
1 atmospheric pressure (atm)
= 760 mmHg (torr) = 76 cmHg
= 76 · 13.6 g/cm
3
(density of mercury)
= 1033.6 g/cm = 1.0336 kg/cm
2
Therefore, 3.5 kg/cm of compressed air is equal
2
to 3.4 atm. To grasp the potential energy of
this pressure, you have to realize that mercury
is 13 times denser than water. So, a pressure of
3.4 atm equates to the pressure of a 1-by-1 cm
column of mercury that is 76 cm tall, or a 1-by-1
cm column of water that is 35 meters tall! That is
the height of a 10-story building! This is why you
can power your models with the energy created
by simply pumping air into the air+water tank.
HOW TO OPERATE THE AIR+WATER TURBINE
1. Fill the air+water tank about half full of water and attach it onto the system. Pump the pump about 10 times
to get all water from water storage tank into the pressurized air+water tank, and keep pumping another 40
times to compress the air and build up the pressure in the air+water tank.
2. Move the level of the one-way switch to open it.
3.
The released water will spray out and strike the blades of the water wheel to activate the
air+water turbine, and drive the geared mechanism behind it. The water then flows out
through the exit nozzle and returns to the water storage tank for repeated use.
Step 1 Pump 50 times.
...which drives the geared mechanism behind it.
