Given emerging technology â and a contracting economy â health plans are looking hard at whether carve-outs for pharmacy benefits, disease management, specialty pharmacy, and behavioral health care are worth the money.
1 The speed in high-grit sewage handling systems should not exceed 12 ft/sec. 2  The flow and velocity in sewage systems with low grit concentrations should not exceed 18 ft/sec.
Slow-moving water implies large-diameter pipes, which would cost more to install. The key question is, how much noise will people accept? Most sources recommend that the speed of water in pipes should be kept to less than 2 m/sec, and some specify a maximum speed of 1.5 or even 1 m/sec. Remember the Slug. The Reynolds numbers corresponding to usable water speeds for each size of pipe are summarised here.
