This text investigates the application of computational methods to optimize the design of machinery and dies used in polymer processing. Natti S. Rao, an expert in polymer engineering, provides a technical framework that bridges the gap between theoretical fluid dynamics and practical industrial manufacturing. By utilizing FORTRAN and BASIC programming, the author establishes a systematic approach for calculating flow patterns, pressure drops, and thermal distribution within processing equipment. The work serves as a bridge between traditional mechanical engineering principles and the emerging digital tools of the era.

Experts recognize this work as a specialized technical manual for engineers involved in the design of polymer processing equipment. Readers frequently note the high level of mathematical rigor and the specific utility of the provided code for legacy system integration.
