The sediment settling velocity, ωs (ms-1) in stagnant water is dependent on the sediment diameter, d (m), sediment density, ρs (kgm-3), water density, ρ (kgm-3),dynamic viscosity of water, μ (kgm-1 s-1), and gravitational acceleration, g (ms-2).By applying the dimensional analysis, develop the equation in terms of phi, π to
explain the ωs.

A water tower supplies water to a city through a pipe with 1 ft diameter. The pipe is 0.5 miles long and is made of commercial steel pipe. Over the years, the supply line lost head and engineers are considering the replacement of 94 percent of the pipe length with a larger diameter pipe (same type). The peak water demand is 3.53 ft3/sec. How much pressure head could be gained by this strategy?
