Conclusions

  1. 1.

    It has been shown that the value of the hydraulic resistance of the accelerated section is a single-valued function of such easily determined averaged parameters as the free-fall rate, the velocity of the gas flow, the mass-flow concentration of particles in the accelerated section, and the diameter of the pipeline.

  2. 2.

    Starting from the dependences obtained, a dimensionless equation has been proposed (12) to determine the losses of heat due to acceleration of the particles of homogeneous materials, with free-fall velocities from 3.21 to 15.03 m/sec, in vertical pipelines with a diameter from 0.028 to 0.050 m.
