5 Function Of Storage Reservoir The storage reservoirs are generally provided in the distribution system to store clear treated water before it is distributed to the consumer. The following 5 functions of the storage reservoir are: 1. They help the pump to run at a uniform rate. 2. They provide the facility of storage … Continue reading 5 Function Of Storage Reservoir
Grid Iron System ⇛ Grid iron system is one method of the layout of distribution pipes. This system is also known as interlaced system or reticulation system. ⇛ In this system, the mains, sub-mains, and branches are interconnected with each other. Thus, this system provides free circulation of water through the pipelines. ⇛ Cut-off valves … Continue reading Grid Iron System- And their Advantages & Disadvantages
Dead End System Dead end system is one method of the layout of distribution pipes. This method is also known as a tree system. It consists of one supply main from which sub-mains are taken. From the sub-mains, the branch lines are provided from which service connections are given to the consumers. The dead-end system of the … Continue reading Dead End System – And Their Advantages and Disadvantages

Design speed 85 km/h allowable rate of change of centrifugal acceleration is … Continue reading Length Of A Valley Curve Problem and Their Solution
6 Stopping Sight Distance Formula The stopping sight distance formula, based on the road surface condition and speed of the vehicle units(m/sec or km/h) is divided into 6 types: A. Level Surface With Friction Coefficient Stopping Sight distance formula(SSD) for the level surface with a coefficient of friction: 1. SSD = Vt + V2/2gf (when … Continue reading 6 Stopping Sight Distance Formula – Highway Engineering
Blaney Criddle Method A simplified formula develops by Blaney and Criddle (1950) in which it correlates the consumptive use of water with the temperature and daytime hours. By multiplying the mean monthly temperature t by the mean monthly percentage p of the maximum possible daytime hours of the year. A monthly consumptive use factor f is determined by this … Continue reading Blaney Criddle Method Formula is used to Determine Consumptive use of water
