Theory bites are a collection of basic hydraulic theory and will touch upon pump design and other areas of pump industry knowledge.
In turbomachinery, a velocity triangle or a velocity diagram is a triangle representing the various components of velocities of the working fluid in a turbomachine. Velocity triangles may be drawn for both the inlet and outlet sections of any turbomachine.
The vector nature of velocity is utilized in the triangles, and the most basic form of a velocity triangle consists of the tangential velocity, the absolute velocity, and the relative velocity of the fluid making up three sides of the triangle.
