In this 2nd report, the authors, from the results of the 1st report, have derived a calculation method to obtain the pressure drop along a straight pipe when the groups of particles of quartz as well as coal are transported in the horizontal pipe, and ascertained that the experimental results were in close accordance with the calculated methods mentioned above. At first, the calculation method and the experiments were limited in the case of straight and horizontal pipe and the air velocities at inlet and outlet of the pipe are equal. And then they derived the Gasterstadt's experimental formula theoretically using the time base instead of the distance base which was used by Gasterstadt. Next, the authors discussed the calculation methods required to convey the mass of pieces by the air current in a long pipe, taking into consideration the variation of air density, coefficient of resistance between air and pipe and pieces velocity consequently the variation of air velocities along a horizontal straight pipe and showed some calculation examples.
