design of water supply distribution system pdf
by
It is the maximum water consumption during any one day in the year. Daily consumption = Avg. daily Consumption x population. Here f = 0.0046 and length = 87.3m , velocity is usually from 5ft/sec so convert it in meter we get 1.524m/sec Only available up to 350mm diameter and mainly used for domestic purposes. daily consumption. 0.03465 = π .
So the Total head becomes now 9.114 + 9.114 + 3.048 + 0.498 + 20+20 = H = 61.7m, BHP = Gama*Q*H / 550 * nu (efficiency) The same basic concepts and principles apply to small community water systems and large city water systems. It was used for a long time as non corrosive and economical alternative to cast iron. The water supply system must provide flows of
water supply systems.
So, the Length of Strainer comes out to be 9m If topographic conditions are ideal, gravity distribution is used.This requires a reservoir at a sufficient elevation above the city so that water can reach to any part of the distribution system with adequate pressure without pumping.If pumping is necessary, water may be pumped directly into closed distribution lines, or it may be pumped into distribution reservoirs which serve to equalize pumping rates throughout the day and provide for pe…
3. Required fields are marked *.
A brief Review of the pipes is given below. sir, wer did u get the length of 87.3 in the design of tubewell? Water Supply Design. It is about 150 to 180 % of the avg. Post was not sent - check your email addresses! = (62.4*1.2375*201.345)/(550*0.6)

Diameter of strainer is usually 10” The Maximum diameter pipes have been provided at the Tank as there will be more pressure. What is a procedure of nodal demand and distribution ? Water Supply Design Corrosion may reduce the capacity by 70%. The distribution system includes pumps, reservoirs, valves, water meter, pipe fittings, etc. So we round our diameter to 200mm and thus the velocity will also change to v = 1.103m/sec Sorry, your blog cannot share posts by email. That it be colorless and clear. Inexpensive, easy to install, small pumping cost. In present study, it was inevitable to design a water supply system for selected area to provide safe water supply design for a small community. Now we don’t have the value of d . Water Supply Design, Cast iron pipe when used in water mains is selected on the basis of maximum working pressures and laying conditions. I want to become a member … how do I apply for it ?
Similar to cast iron pipe except with increased ductility.
For distribution system design period is 25-years (difficult to replace), Reasonable economics of scale are achieved. (3) Supply line. Volume of Water for storage = Q x t = 83.16 x 8 = 665.28 m3 The supply system within the site Drainage a. Output is attached with this report showing all the necessary data required for designing process. The city water distribution main to the site b. They are available generally in 100mm-600mm diameter.
A good water distribution system aims to supply water to all the consumers whenever required in sufficient quantity with required pressure without any leakage. Water Supply Design Maximum Daily consumption = 1.5 x Avg. The pipe is subject to corrosion from water; however the initial rate of corrosion is not as great as that of steel.
bro i need excel sheet for its calculation, epanet text file file isn’t opening please help me, I am a registered member but i cant find any excel file here, Excel Files are available here only https://civilengineerspk.com/excel-sheets/. Prof van Zyl’s research focuses on water distribution systems, and his current interests include hydraulic modelling, impact of pressure on leakage, reliability of bulk supply systems and water demand management.
Water Supply Design, (adsbygoogle = window.adsbygoogle || []).push({}); Water System Design Manual December 2009 For more information or additional copies of this publication contact: Office of Drinking Water Constituent Services Section Department of Health PO Box 47828 Olympia, WA 98504 For tube well, design period is 5-years (easy to install).
Duration for storage = 8 hrs Water Supply Design, Following are some major types of pipes commonly used in water supply system, All the above described pipes have their own merits and demerits. The purpose of this project is to design the “Water Distribution Scheme” for a society which includes the Diameter of pipes, Lengths of Pipes, Pressure in pipes, Turbine Motor, Storage Tank and Strainer length. d. L x 0.04m/sec Water Supply Design V = 0.02 – 0.06 m/sec …..let us take v = 0.04m/sec
Q= 23.1liter/sec = 0.0231m3/sec x 1.5 = 0.03465m3/sec So this economical project of Water Distribution Scheme is successfully completed and all the results are attached at the end of the report. … Increased bend ability with Diameter of Pipes: Rate of interest (design period is shorter), Too frequent extension in water supply system is not possible.
