Kuj kom paub, koj yuav nrhiav tau lub vojvoog hydraulic li cas?

Los ntawm hydraulic vojvoog txhais: RH = A/P, qhov twg A yog qhov chaw hla ntu ntawm ntws thiab P yog nws qhov chaw ntub dej. Los ntawm daim duab qhia meej tias A = los ntawm thiab P = 2y + b, yog li cov hydraulic vojvoog yog: RH = by/(2y + b) rau qhov qhib channel ntws los ntawm cov kab hla hla.
