The force of the water jet is adjusted via the flow rate. Experiments study the influence of flow velocity and amount of flow rate as well as of different deflection angles. The forces are calculated using the momentum equation and compared with the measurements. The jet forces generated by the water jet are measured on the weight-loaded scale. During deceleration, acceleration and deflection of a flowing fluid, there is a change of velocity that leads to a change in momentum. In jet forces are generated and studied with the aid of a water jet that acts on an interchangeable deflector. The experimental unit includes a transparent tank, a nozzle, four interchangeable deflectors with different deflection angles and a weight-loaded scale. According to the momentum equation these changes result in forces. In practice, the motive forces are used to convert kinetic energy into work done, for example in a Pelton turbine. A water jet exits a nozzle vertically upwards, hits the deflector and is deflected.
