Wheel chamber is a chamber provided on HP side of after impulse wheel.
The most of the (>50% of pressure at rated load) drops at wheel chamber,..AT lower load wheel chamber pressure drops.
As a thumb rule wheel chamber pressure is calculated as
Turbine wheel chamber pressure (kg/cm2) = (Turbine inlet pressure (kg/cm2) X Turbine operating load (MW) X 0.6)/Turbine rated capacity (MW).
