| Abstract: | Air vessels offer an effective means of reducing water hammer overpressures and negative pressures due to pump trip in pipelines. The process of sizing air vessels is simplified with the nomographs presented. Both air volume and total vessel size are calculated. The size can be minimized by correct selection of outlet and inlet connector diameter, and guides are provided to make these selections. |
