> Force due to Pipe Bend - new calculation

> We added a new calculation to our website on March 12. It computes the
reaction force required to hold a pipe bend in place as a fluid flows around a horizontal bend in a pipe. In order to properly size thrust blocks, hangars, or other devices to hold a pipe in place, the momentum equation is used to compute the necessary resistive force to hold the pipe stationary.
>
> Forces in a pipe bend in the horizontal plane are caused by the
fluid's momentum and pressure. If the pipe undergoes a bend in the vertical plane, where the entrance to the bend is above the exit (or vice-versa), then the weight of the liquid and pipe material within the bend will contribute to the force. Since computing the volume of fluid and pipe material within a bend requires considerably more input, we kept our calculation relatively simple by keeping it in the horizontal plane.
>
> The calculation displays the reaction force in two ways:
> 1. The x and y components of the reaction force are shown, and
> 2. The resultant force and its direction are shown.
>
> Equations and flow diagrams can be seen on the web page. The
calculation has a demonstration mode so that you can enter different variables and see the results.
