##### Turbomachinery Tools

Here is a tool which draws the exit velocity triangle over a Pelton Wheel runner, and helps to study the parametric variations on the exit velocity triangle. Further, it also computes parameters such as Peripheral velocity, absolute velocity, flow velocity, relative velocity and whirl component of velocity at exit.

Here is a tool which draws the inlet and exit velocity triangles over a Francis/Kaplan turbine runner, and helps to study the parametric variations on the velocity triangles. Further, it also computes parameters such as Peripheral velocity, absolute velocity, flow velocity, relative velocity and whirl component of velocity at exit.

Here is a tool which draws the inlet and exit velocity triangles over a Centrifugal pump impeller, and helps to study the parametric variations on the exit velocity triangle. Further, it also computes parameters such as Peripheral velocity, absolute velocity, flow velocity, relative velocity, whirl component of velocity at exit and vane outlet angle.

Here is a tool which suggests what hydraulic turbine should be selected based on the input power, flow rate, head, revolutions per minute and blade diameter. Further, values of power coefficient, flow coefficient, head coefficient and dimensional specific speed are provided as outputs along with plots showing trends in these property variations.
