摘要
通过实验测试了聚氨酯、橡胶、PVC等新型消防水带的水头损失,在实验基础上运用水力学理论,获得了新型消防水带的沿程阻力系数值,分析了其在主要供水流量控制范围内的水流流态、水力分区和粗糙度,并建立了其沿程阻力系数与水流流态和粗糙度等水力特性之间的关系曲线图。
The head loss of rubber-lined, PU--lined and PVC-- lined fire hose was tested by experiment. Based on the experi ment, and using hydraulics theory, the friction factor was gotten, the flow regime, turbulence hydraulic sections and the internal roughness factor at main water flow control range were analyzed, and the chart of fire hose correlated friction factor, Re and internal roughness factor was created for application.
