This standard was first published in 1993. This revision of the standard has been brought out based on wide field experience and international practices, also updating the references. In this revision, the major changes that have been made are as follows:
a) The definition and formula of specific speed has been updated;
b) Maximum tail water level has been defined;
c) Sketches of relationship between specific speed and rated head for Francis and Kaplan turbines have been updated;
d) For the calculation of suction head, the temperature condition has been updated;
e) Mathematical equations for various parameters have been given along with their sketches;
f) Addition of a minimum margin for deeper setting of turbine from calculated values has been specified;
g) Provision for calculation of length of stator frame has been updated; and
h) Formula for calculation of weight of generator rotor has been added and the old sketch meant for its calculation has been deleted.
