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.
High flow rates over long periods of time can cause pipe erosion in the piping and especially in elbows and T fittings. Typically building codes limit the water velocity in hot water piping to 5 to 8 feet per second to prevent erosion of the pipe and fittings.Five feet per second is moving right along. At that velocity the hot water should reach a fixture connected to the water heater with a 100 foot pipe in about 20 seconds..74. 1.93. If your pipe is 3/4, then at 5 gallons per minute the flow rate would be 3.29 feet per second, so a 100 foot long pipe would require about 30 seconds. If the pipe was 1/2, then it would only take about 15 seconds to get the hot water through the 100 foot long pipe.
