A simplified technique for prediction of pressure distribution, velocity profiles, torque, and power requirements for the calendering of power‐law fluids is presented. The technique assumes isothermal conditions, is based on the lubrication approximation and Gaskell's analysis, and uses melt flow index as the only temperature‐dependent resin parameter for the prediction. The predictions are found to compare favorably with those made by Vlachopoulos and Hrymak for rigid PVC.
