Can anyone point out how a reaction turbine works in detail?

Relation b/w the face to which fluid enters and the direction of rotation?

Reaction turbines have been named as "Reaction" because its blades are so designed that when fluid flow over it and because of streamlined design(refer to design of wings which are streamlined), the fluid flowing above the blade surface and below the blade surface are having different velocities which makes the pressure difference(as said in Bernoulli equation the energy is same throughout, hence reduction in velocity changes result in pressure changes to keep the amount constant)  above and below the surface, and this pressure difference initiates the movement of blade towards low pressure region, giving rise to movement of blades.

Within this Reaction turbine the velocity of the blades are due the loss pf pressure energy of the fluid(whereas in impulse turbine its all due to impulse effect of fluid against the blade which moves the blades, pressure remains the same whereas the momentum is decreased by the fluid which is gained by the blades)
