Unable to run Pressure Zone Analysis tools?

[dineshpatil2]

Pressure Zone Analysis tool has inbuilt tools and the tools are: 1.Minimum and Maximum Pressure Contour,

2. Minimum and Maximum Pressure Raster, 3. Pressure Zone Elevation, 4.  Pressure Zone to Feature and 5. Select and Export.

I tried to run the each tool. But, I got message "Tool is not licensed". 

What kind of Licences is required to run this tools?
