Equilateral triangular sewer, 1.5 m on each side, constructed of concrete, used to drain at a flow rate of 1000 kg / m 5, with the effluent density of 1100 kg / m and viscosity of 1.25 cP, length 10. km before entering the center. Calculate 1.1 The area of contact with the sewage of the pipe (Perimeter of pipe, P) is equal to how many meters?
1.2 The cross-sectional area of the sewer. (Goss-sectional are, A) is how many square meters?
1.3 What is the hydraulic radius, R. Since the in-pipe flow (h) is equal to the water meter when calculated with the Hazen Williams Formula, it has a Hazen-Williams constant of 110 1.6 What is the system pressure drop in kPa 1.7 The power of the pump at How many watts must be compensated for the system when the pump efficiency is 0.85 1.8 Reynolds number of particles?
