{wiki=Euler's_pump_and_turbine_equation}

Euler's pump and turbine equation relates the mechanical energy transfer in fluid machines like pumps and turbines to the change in pressure, velocity, and elevation as fluid passes through them. The equation is derived from Euler's equation of motion for fluid dynamics and captures how energy is added or extracted from a flowing fluid.
