Hazen - Williams

Used for primarily water lines associated with production facilities. Limited to Reynolds numbers in the range of Re = 4,000 to 1,000000. Its chief drawback is that the Hazen-Williams coefficient is largely an experience factor which also depends on the viscosity of the product flowing.
