The gravitational vortex water turbine puts small hydro on ... output and efficiency. The maximum hydraulic power output of the turbine is given by: P = rgQHv watt (1). where: H v = Height of vortex (m). Q = Flow rate (m 3 /s). g = Gravitational constant. r = Water density (kg/m 3). A maximum hydraulic output of 1 kW can be obtained with a flow rate of only 0,1 m 3 and a head of only 0,6 m.
