Molecular formula : CAS :
nature : hydraulic radius rh the definition of the freedom of fluid channel A cross-sectional area and the surrounding wetting L ratio, rh = A / L. For circular tube, A = π d2 / 4, L = π d, hydraulic radius rh = d / 4, the diameter d of hydraulic radius of four times. For non-circular channels or casing Gap in the fluid flow, as defined above can be obtained its hydraulic radius rh value, and then to four times the hydraulic radius rh value of the diameter d considerable volume, known as the equivalent diameter de that de = 4rh.
