Subject aims expressed by acquired skills and competences
Student will acquire knowledge of the flow of suspension fluid (water, air) - a solid particle. The energy flow equations and the Bingham equation are mainly used for laminar flow of non-Newtonian fluids (suspensions). The student will be acquainted in detail with the calculation of the pressure gradient in turbulent flow of suspensions, determination of the critical flow rate, with the design of a centrifugal pump, fan and optimization of the operating point. The student will be acquainted with the applications of hydraulic (transport of water and coal) and pneumatic (pipe mail) transport and the possibilities of mathematical modelling of flow with particles. The student will be able to design a circuit for the transport of solid particles in a fluid.

Summary
The subject Logistics transmission media to acquaint students with the calculation of basic hydraulic parameters of suspensions flow - liquid (water, air) - solid particles. The subject is addressed the issue of physical properties of transported materials (grading curve) and dispersion systems (concentration, viscosity of suspensions), the movement of material particles in the fluid flow (sedimentation velocity, velocity of suspension) and will also explain the issue of flow modelling with particles. Furthermore, the subject deals with the technology of hydraulic and pneumatic transport. Applications of hydraulic transport (transport of coal in liquid, floating excavators and others) and pneumatic transport (transport of solid particles in the airflow, pipe mail and others) in practice will be discussed in the subject.
