performance of water supply networks under water hammer phenomenon based on sustainability coefficient (case study: feridonshahr water supply network)

sustainability of water supply networks should be based on the risks of water hammer phenomenon. the purpose of this study is to provide a new approach to the analysis of water hammer phenomenon in the water supply network. by conventional methods, the damage because of water hammer is estimated based on the maximum pressure at nodes. however, during this phenomenon continuation and changing of...

Assessment of water supply system and water quality of Lighvan village using water safety plan

Background: Continuous expansion of potable water pollution sources is one of the main concerns of water suppliers, therefore measures such as water safety plan (WSP), have been taken into account to control these sources of pollution. The aim of this study was to identify probable risks and threatening hazards to drinking water quality in Lighvan village along with assessment of bank filtratio...

An Artificial Neural Network Model for Predicting the Pressure Gradient in Horizontal Oil–Water Separated Flow

In this study, a three–layer artificial neural network (ANN) model was developed to predict the pressure gradient in horizontal liquid–liquid separated flow. A total of 455 data points were collected from 13 data sources to develop the ANN model. Superficial velocities, viscosity ratio and density ratio of oil to water, and roughness and inner diameter of pipe were used as input parameters of ...
