Impulse Turbine Newtons Second Law as long as an Impulse Blade: The tangential as long as ce acting of the jet is: F = mass flow rate X Change of velocity in the tangential direction Tangential relative velocity at blade Inlet : Vri cos(bi). Tangential relative velocity at blade exit : -Vre cos(be). Change in velocity in tangential direction: -Vre cos(be) – Vri cos(bi). -(Vre cos(be) + Vri cos(bi)). Tanential Force, The reaction to this as long as ce provides the driving thrust on the wheel. The driving as long as ce on wheel Power Output of the blade, Diagram Efficiency or Blade efficiency:

Define Blade Speed Ratio, f For a given shape of the blade, the efficiency is a strong function of f. For maximum efficiency:

The reaction to this as long as ce provides the driving thrust on the wheel. The driving as long as ce on wheel Power Output of the blade, Diagram Efficiency or Blade efficiency: First law as long as fixed blades: First law as long as moving blades:

Losses in nozzle, Nozzle blade loss factor, f For a given shape of the blade, the efficiency is a strong function of U/Va1. For maximum efficiency:
