In hydraulic systems, the flow rate of the fluid may be considered as a through variable, and the pressure causing the flow may be the across variable . 在水利学系统中,流体的流速可考虑作流通变量,而引起流动的压力可考虑作跨接变量。
If an aerosol counter is used to monitor the concentration of particles in the emerging air, one finds that the concentration falls off with decreasing flow rate . 如果用一台气溶胶计数器检测射出气流中的粒子浓度,就会发现浓度随流速的降低而减少。
2high lift , large flow rate and corrosion resistance make 2扬程高流量大抗腐蚀。
