Pressure Estimation

Combined extrusion processes can be in demand in the production of body products with jumper in the central part and thin walls. Often, their industrial implementation requires theoretical justiﬁ cation of power regimes. Mathematical model of combined extrusion created on the basis of the upper estimates method is presented. The effect of technological parameters on extrusion force is established based on the obtained expressions for pressure estimation.

Integrated System Design

Several long-distance, high-volume coal slurry transportation systems are planned or proposed for the United States. These new systems offer a method of transport that is both economical and environmentally attractive. The design of these systems will be a challenge to the pipeline engineer since an integrated, system design of several components is necessary to achieve an optimum overall effect. The pipeline, pump stations, instrumentation and controls, slurry preparation, and utilization facilities must all be considered in the design. The purpose of this paper is to describe the system components of a large coal slurry transportation system in detail and to show the special design considerations required for the overall system design considering the interrelationships of the various components.
