In the case of the LH turbines, the propeller turbine is normally near to the surface in an
elevated flume. You can measure the head from the intake surface level down to the water
surface in the tailrace below.
3.1.2. Estimating the power output
A rough estimate of generation potential can be calculated as follows:
Generation (Watts) = head (metres) x flow (litres per second) x 5
Generation (Watts) = head (feet) x flow (gallons per minute) / 10
Standard PowerSpout turbines are rated for up to 1200 W but a special high power (HP)
version is available that is capable of 1.6 kW at 1600 rpm, given suitable water pressure and
flow conditions. Maximum current that the turbine wiring can carry is 32 amps as standard;
an upgrade to 50 amps is available on request for high power low voltage applications (fee
applies).
