Unit quantities are unit flow, unit power, and unit speed. They are used in hydraulic turbines. 

Unit quantities are used to compare the performance of turbines with different outputs, speeds, and heads. 

The unit quantities for a turbine are:
Unit speed:
The speed of a turbine working under a unit head. It is denoted by 'Nu'.
Unit discharge: The discharge passing through a turbine working under a unit head. It is denoted by 'Qu'. 
Unit power: The power developed by a turbine working under a unit head. It is denoted by 'Pu'.
