In order to predict the behaviour of a turbine working under a varying condition of head, speed output, etc, the results are expressed in terms of quantities that may be obtained when the head on the turbine is reduced to unity.
The following are three important unit quantities.
|
Unit speed |
Speed of turbine working under |
\({N_u} = \frac{N}{{\sqrt H }}\) |
|
Unit discharge |
Discharge passing through a turbine |
\({Q_u} = \frac{Q}{{\sqrt H }}\) |
|
Unit power |
Power developed by a turbine working under unit head |
\({P_u} = \frac{P}{{{H^{3/2}}}}\) |
