WebbIn fluid mechanics, pressure head is the height of a liquid column that corresponds to a particular pressure exerted by the liquid column on the base of its container. It may also be called static pressure head or simply static head (but not static head pressure).. Mathematically this is expressed as: = = where is pressure head (which is actually a … Webb5.15.3.2.6.1.1 Blade pitch angle control. With respect to rotor’s blade angle facing to air, a turbine can be stall regulated or pitch regulated. In first type, the blade’s pitch angle never changes (or changes only at a little value) and only stall characteristics of the blade affect the rotor speed and mechanical power.
