The water is channeled through an intake gate and into
canal race with U-shaped cross section to reduce water friction.
The cross section area of the canal race is approximately one
square meter. The figure is estimated using linear interpolation
from existing canal race designs on several micro hydro around
Indonesia. To ensure smooth and continuous supply of water
into penstock, the water is stored in the for eBay. The size of
the bay is also estimated using similar approach as in sizing the
canal race which yields bay volume of 15 cubic meters.
