See AnswerQ: Water is transported by gravity through a 10-cm diameter 550
Water is transported by gravity through a 10-cm diameter 550-m-long plastic pipe with an elevation gradient of 0.01 (i.e., an elevation drop of 1 m per 100 m of pipe length). Taking ρ = 1000 kg/m3 and...
See AnswerQ: Water to a residential area is transported at a rate of 1
Water to a residential area is transported at a rate of 1.5 m3/s via 70-cm-internal-diameter concrete pipes with a surface roughness of 3 mm and a total length of 1500 m. In order to reduce pumping po...
See AnswerQ: Two pipes of identical length and material are connected in parallel.
Two pipes of identical length and material are connected in parallel. The diameter of pipe A is twice the diameter of pipe B. Assuming the friction factor to be the same in both cases and disregarding...
See AnswerQ: In a laminar flow through a circular tube of radius of R
In a laminar flow through a circular tube of radius of R, the velocity and temperature profiles at a cross section are given by u = u0(1 − r2/R2) and T(r) = A + Br2 − Cr4 where A, B, and C are positiv...
See AnswerQ: In a geothermal district heating system, 10,000 kg/
In a geothermal district heating system, 10,000 kg/s of hot water must be delivered a distance of 10 km in a horizontal pipe. The minor losses are negligible, and the only significant energy loss aris...
