1 atmospheric pressure (atm)
= 760 mmHg (torr) = 76 cmHg
= 76 · 13.6 g/cm
3 (density of mercury)
= 1033.6 g/cm 2 = 1.0336 kg/cm 2
Therefore, 3.5 kg/cm 2 of compressed air is
equal to 3.4 atm. To grasp the potential en-
ergy 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 pres-
sure 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 sim-
ply pumping air into the air+water tank.
HOW TO OPERATE THE AIR+WATER TURBINE
1. 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. Step 2 Turn on the switch... Step 3 ...to spin the turbine...
...which drives the geared mechanism behind it. The model begins to move!
