P = Q g h, where ! P is the power in watts !
is the turbine efficiency coefficient (dimensionless)
KNOWLEDGE BETTERMENT for the
is the water density in kg / m3
!
! Q is the flow in m3 / s ! g is the acceleration of gravity ! h is the difference in height between inlet and outlet https://en.wikipedia.org/wiki/Hydropower Flow in a Tube (Manning) ! Q = 1 / n A (r / 2) ^ (2/3) S ! Q = Water flow - m / s ! A = The cross-sectional area - m ! n is coefficient of friction (eg 0.009 for plastic) ! S slope of the pipe Q = 1 / n A (r / 2) ^ (2/3) S With plastic pipes and a pipe diameter of 20 cm = 0.02 meters Area of pipe "A" = r = (0.1 meter) S = 35 / 90
Q = 1 / n A (r / 2) ^ (2/3) S = 1 / 0.009 x (0.1x0.1) x (0.1 / 2) ^ (1/3) x (35/90) = 1 / 0.009 x (0.1x0.1) x (0.0025) ((1/3) x 0.38 = 1 / 0.009 x (0.01) x (2.5) ((1/3) / 10 x0.615 = 1 / 0.009 x 0.01 x 1.36 / 10 x 0.6 = 0, 3 m / s
