Conclusions Optimal design of a sewer involves determination of combination of slope and diameter so as to obtain the least cost design along with the satisfaction of various constraints.

However,being empirical, the Hazen-Williams equation is not dimen-sionally homogeneous and its range williama applicability is limited. For example, by substituting the f in the explicit ap-proximation formula of Swamee and Jain 0. The variation in the cost of sewer line versus option number is shown in Fig. Each curve inthis figure corresponds to an ID.

The optimal solution of sewer line is given in Table 5. Determination of upstream and downstream depths of sewers; and 4. Determination of the set of feasible diameters; 2.

Hazen–Williams equation

Henri Pitot discovered that the velocity of a fluid was proportional to the square williama of its head in the early 18th century. The C is the Hazen-Williams coefficient. Excavation of sewer trenches; and 3.


This transformation also allows theerror of a misapplied Hazen-Williams equation to be quanti-fied. However, the exponents were selected representing “ap-proximately average conditions” so that C is practically con-stant and is viewed as an index of the smoothness of the in-terior of the pipe surface. This intent of C and the fact thathydraulic radius appears separately in the Hazen-Williamsequation might have motivated many texts, references, andsoftware manuals [e.

Determination of the total cost of sewer.

The Moody diagram Moody facilitates the determina-tion of this friction factor, which is implicit in the Colebrook-White formula. Let e be the equivalent roughness of the pipeinner wiliams. This page was last edited on 13 Marchat Water at 60 F The Darcy-Weisbach equation was difficult to use because the friction factor was difficult to estimate.

The second objective of this paper is to show such atransformation.

The program computes velocities, water depths, pipe slopes, and inverts corresponding to inputted diameters, flows, pipe lengths, ground elevations, and design criteria. Archived from the original on The optimal design obtained with Manning equation is The data adopted for Li, Qi and Zi have been used to design the 2-link sewer line, and is given in Table 3.

wilpiams The first 14 sets pertainingto new cast iron pipes are used here to demonstrate the vari-ation of C with R and D. The cost structure williamx the following components of a sewer line is described as follows: Hazen-Williams Equation Module 3c: This, com-bined with Dlv O.

Tuberias Hazen y Williams Documents. The friction factor is related tothe Reynolds number R and the equivalent roughness e, andthe pipe diameter D by the Colebrook-White formulaI E 2.

A portion ofthat table is reproduced in Table 1. A method for doing so is given.

The Manning equation is applicable for rough turbulent flow and the Hazen-Williams equation for smooth turbulent flow whereas the Darcy-Weisbach equation is applicable for laminar as well as turbulent flow Liou, Schematic diagram of a sewer The 2-link sewer line problem was solved by both Hazen-Williams and Manning equations. Cost of earthwork; and 2.
