Problem1 It is known that for a laminar flow through a round pipe φ(D)-32 VD, where "I" and "D" are length and diameter of the pipe, respectively. Consider a fully developed, laminar flow Q- through two horizontal smooth pipes of equal length. The pressure drop for the first pipe is 1.44 times greater than is for the second pipe. If the diameter of the first pipe is D, determine the diameter of the second pipe. Neglect the minor losses.

A pipe with an inner diameter of 8 inches (0.67 ft) carries water (ρ = 62.4 lbm/ft3, μ = 6.72 x 10-4 lbm/ft ⋅s) horizontally at a flow rate of 3.1 ft3/s. The pipe has been in service for a very long time, so the wall surface has become fairly rough (ε = 0.008 inches). The pipe is 1550 ft long. A) Calculate ΔP over the pipe length in psi B) Suppose the old pipe is now replaced with a...

Disinfection is conducted in a pipe attached to a tank. The pipe diameter is 18 inches and length is 90 ft. The tank volume is 115,000 gallons and it contains a baffled inlet with some intra-basin baffles. The residual coming out of the tank is to be 0.2 mg/L. The water pH is 8.0 and the lowest temperature is 10°C. Determine: a) How much flow can be treated if using free chlorine for 4-log virus removal (gal/d)? b) How much...
