In this study the author obtained theoretically the head H (m) to be given in the delivery of pump and the water horse power N (FP) from the equation of “Equilobrium of Energy” in the transportation of coal by the vertical pipe H₀ (m).
Then by considering the efficiency ofp ump the shaft horse power N'(FP) and so the theoretical and actual efficiency of transporting coal were obtained.
Consequently in the case of changing the diameter of pipe, the effects upon the characteristics and efficiency were discussed by the numerical calculations.
