Prediction of pressure drop in multiphase horizontal pipe flow [PDF]

open access: yes, 2006
Empirical correlations were tested against reliable two phase pipe flow data for the prediction of pressure drop. Correlations are recommended for the prediction with stratified and annular type flows.

A Novel Temperature vs Pessure drop Grid Diagram for Energy Saving in Heat Exchanger Network Retrofit

open access: yesChemical Engineering Transactions, 2022
Pressure drop in the heat exchanger is a key issue that should be considered in the HEN retrofit, as increasing the pressure of fluid can cost a substantial amount of energy. To accurately estimate the cost-related trade-off factors, the relative cost of
