Pharmaceutical Engineering Practical Manual (Unit Operations)

The Second Edition of the Practical Manual is necessitated for inclusion of the following important experiments:• Organised substances by Percolation Method• Continuous Hot Extraction Method• Factors affecting the Rate of Evaporation• Effect of Particle size on Sedimentation Rate As usual, the Practical Manual is written in lucid language and self-explanatory form. This expanded version is now more comprehensive and student friendly and B.Pharma students will highly benefit. Contents 1. Determination of Radiation Constant of Iron Cylinder 2.
