The various measurements show how to properly construct and set up your system.
The lower diagram (Canal – Plan View) shows the precise internal measurements in
order to construct the water intake canal.
SELECTING A SITE
PowerPal is designed for use in a wide range of locations. The most critical factor is
sufficient water flow. Water flow is the amount of water that passes through the
turbine at any instant, measured in liters per second (l/sec). The second important
factor is head (see below). The following table shows the minimum flow rate and
head to achieve the quoted power output for each model:
Flow (l/sec):
Head (m):
Measuring Flow
Flow can be calculated approximately by knowing the water speed. This speed,
multiplied by the cross-sectional area of the intake canal will give you an idea of the
flow rate. Minimum water flow speeds for each model are:
MHG-200LH:
0.54 m/sec.
MHG-500LH:
0.50 m/sec.
MHG-1000LH:
0.41 m/sec.
As a rule, say half a meter per second, or 5 meters in 10 seconds. Drop a leaf
upstream and read the time it takes to travel the measured distance. Note that this
method is only a guide and you will need a sufficient volume of water flowing at this
rate to make the larger models work.
Measuring Head
The head is the height from the water surface flowing into the turbine down to the
water surface in the stream below. It is shown in the System Diagram.
This head should be 1.5 meters for all PowerPal models. If it is smaller then the power
output will be reduced. If it is larger then your power output will be increased. While
increased power output appears desirable, if the head is too large then the rotor will
turn too fast and reduce the life of the bearings. Try to keep the head in the range of
1.4 meters to 1.6 meters.
Do not attempt to exceed the recommended head height.
