Abstract
The Part 2 touches upon the pumping properties of sprayed fire protection. The laboratory test was done on the fresh state properties of fire protection and the pumping properties were researched by the field test using various materials. The obtained results are as follows; a) The flow value or cone penetration value as the index of workability has linear relation to the water material ratio for each materials. b) The flow resistance, which is obtainable by dividing pressure loss of unit pipe length by velocity, is correlated with these value at each materials. c) The above results show that the flow value or penetration value is useful as the index for supervision of pumping work.
