Abstract
This Part 3 refers to the flow properties of such sprayed fireprotection materials in pipe as the vermiculite plaster or rock-wool cement mortar. The following results were obtained. a) Assumming that these materials are of Bingham body with the slip layer on the glassy surface of rigid wall, the theoretical equation of flow properties can be expressed as the function of pressure loss, rheorogical properties of used materials, velocity, pipe length and radus of pipe. b) The calculated pressure loss based on this equation has a good agreement with the measurement results on the actual pumping shown by the previous Part of the report.
