Wave Speed Calculator

The wave speed calculator allows you to determine the wave speed for a pipe or set of pipes.

The dialog consists of the following controls:

Bulk Modulus of Elasticity The bulk modulus of elasticity of the liquid. Click the ellipsis button to choose a liquid from the Liquid Engineering Library. Choosing a liquid from the library will populate both this field and the Specific Gravity field with the values for the chosen liquid.
Specific Gravity The specific gravity of the liquid. Click the ellipsis button to choose a liquid from the Liquid Engineering Library. Choosing a liquid from the library will populate both this field and the Bulk Modulus of Elasticity field with the values for the chosen liquid.
Young’s Modulus The Young’s modulus of the elasticity of the pipe material. Click the ellipsis button to choose a material from the Material Engineering Library. Choosing a material from the library will populate both this field and the Poisson’s Ratio field with the values for the chosen material.
Poisson’s Ratio The Poisson’s ratio of the pipe material. Click the ellipsis button to choose a material from the Material Engineering Library. Choosing a material from the library will populate both this field and the Young’s Modulus field with the values for the chosen material.
Wall Thickness The thickness of the pipe wall.
Pipeline Support Select the method of pipeline support.
All When this button is selected, the calculated Wave Speed value will be applied to all pipes in the model.
Selection When this button is selected, the calculated Wave Speed value will be applied to all of the pipes that are currently selected in the model.
Selection Set When this button is selected, the calculated Wave Speed value will be applied to all of the pipes contained within the specified selection set.
