Abstract
In this study, the pressure loss of a fire hose reel hydrant was examined and the effects of each factor on the pressure loss were analyzed. First, in the pressure loss experiment according to the length of the reel hose, the pressure loss increased with increasing length of the reel hose; it was approximately 38.86% based on a 25 m hose. Second, the pressure loss of the reel hose per unit length was estimated to be $.13{\sim}.15kgf/cm^2$. Third, in the pressure loss experiment according to the change in the flow rate, the result was similar to the relation, flow rate - pressure loss (${\Delta}P{\sim}Q^2$), in the piping flow. These results provide basic data on the evaluation of fire pump pressure and the performance-based fire-protecting design of fire hose reel hydrants used in buildings.
