For generalizing the findings in this paper, a dimensionless
relationship between power and flow discharge is sought. To achieve this, Eq. (6) is divided by a reference power (Pr). Pr is assumed
to be the maximum power that can be generated using a reference
discharge (Qr) and a fixed gross head and penstock geometry
(constant CL). For maximum power, the turbine and generator efficiencies need to be 100% (i.e., ht ¼ 100% and hg ¼ 100%). Also,
maximum power for a fixed penstock geometry can be obtained by
setting dP/dQ in Eq. (6) equal to zero, which gives
