... uses a retention time method which sizes the liquid section of the separator. The recommended retention time will be approximately 2 times the API 12J values for 2 reasons: To account for hydraulic short circuiting in the separator To ensure that the separation process is in the Stokes or Laminar...

... generalized framework for developing friction prediction equations. A highly accurate numerical simulator for the comprehensive family of fluids modeled by the GHB model was developed for predicting laminar flow-friction loss in pipes and annuli. The computational method, based on several exact integrals...

... As indicated in Fig. 12 , the high-rheology fluid appears to have been in the laminar-flow regime for the entire range of pump rates. The model predicts transition at higher pump rates and friction factors that continuously decrease through the transition zone. According to the model, the flow...
