TURBINE DESIGN
According to the flow rate and gross head the most suitable turbine is Francis
turbine but construction and maintain is difficulty as well as high cost. We
are going to design larger than 1 kw power plant.

Firstly we assume the
required rpm as 750 rpm from the turbine.
When the flow rate is 15 l/s and the
inlet diameter to the spiral casing is 6cm,the inlet velocity to the turbine
take around 5 m/s. This shows you there is no variation of the flow velocity of
the involute casing and furthermore constant speed. The simulation shows how
the flow velocity varies inside the reaction turbine.
