范宁摩擦系数 meaning in Chinese
fanning friction factor
Examples
- In this paper , the working fluid is air . experimental study of the nine different structure parameters of 3 - d ift with staggered arrangement fins in the reynolds number range of 250 to 30000 is performed to investigate the characteristics of heat transfer and flow friction behavior . analyses and reduces the experimental data by the least square method , obtains the nusselt and fanning friction fitting criterion equations
