Unit Speed, Unit Discharge and Unit Power

What is Unit Speed, Unit Discharge and Unit Power of a turbine? How do we calculate these using formula?

The unit speed is the speed of the turbine operating under one meter head. Mathematically, unit speed,

The unit discharge is the discharge through a turbine when the head on the turbine is unity. Mathematically, unit discharge,

The unit power is the power developed by a turbine when the head on the turbine is unity. Mathematically, unit power,
