SHARED KNOWLEDGE OF ENGINEERING

The word "CIVIL" is related to the  ordinary citizens and their concerns. It is very true that civil engineers are always busy with working for other's benefit. You can not imagine any change without civil engineers. Though it is very rude to hear but it is true that all other engineering comes after civil engineering because civil engineering is related to the one of the basic needs of human being. If you can not live well you can not think about other technologies and to love well you will need civil engineer's help. So civil engineers are serving for the greater goods of human. Here is some greatest quotes by some famous persons about civil engineering; Go for civil engineering, because civil engineering is the branch of engineering which teaches you the most about managing people. Managing people is a skill which is very, very useful and applies almost regardless of what you do. – Sir John Harvey Jones           His father loved him dearly, bu...

Frequently used formulas in pipeline construction; 1. h = f(LV 2 /2Dg) h : Head loss (m) L : Length of pipeline (m) D: Diameter of pipe (m) (Normally nominal diameter presented in meter is used.) V: Flow velocity (m/s) g : Acceleration of gravity (= 9.8 m/s2) f : Head loss coefficient 2. For water pipeline, Hazen-Williams formula is commonly used. V = 0.35464C H D 0.63 I 0.54 Q = 0.27853C H D 2.63 I 0.54 I = 10.666 C H -1.85 D -4.87 Q 1.85  Where, CH : Coefficient For cement mortar or epoxy lined ductile iron pipe, a CH value of 150 can be used; however for design purpose, 130 is recommended, which includes losses in fittings, valves and other facilities, plus some allowance. I : Hydraulic gradient (unit head loss of the pipeline) = h/L Q : Flow volume (m3/s)

Safety First: Essential Safety Practices in Water Pipeline Construction (Ductile Iron Pipe) “Safety First” is not just a slogan—it is a fundamental principle that must guide all construction activities. Given the diverse nature of construction work, safety measures vary depending on the type of activity. However, certain core principles—such as worker safety and public (third-party) safety—remain universally applicable. This document outlines key safety practices specifically relevant to water pipeline construction, particularly for Ductile Iron Pipe (DIP) installations. 1. Site Safety and Access Control Prior to the commencement of any construction activity, the work zone must be clearly demarcated using safety barriers, cones, and caution tapes. The Site Manager must verify that all protective measures are properly installed before authorizing work to begin. Unauthorized personnel and third parties must be strictly prohibited from entering the designated work area. 2. Worker Sa...
