Design an open well in fine sand to give a discharge of 0.03 cumec when worked under a depression head of 2.5 m. April 18, 2023February 2, 2024By Er. Mr. M. V. You Are Here :- Home Page – Civil Engineering Study Materials – Design an open well in fine sand to give a discharge of 0.03 cumec when worked under a depression head of 2.5 m. Data Given, H = 2.5 m Q = 0.03 cumec (m3/s) Q = 0.03 ∗ 3600 m3/hour Q = 108 m3/hour For open wells, Q = (k/A)∙A∙H 108 = 0.50 * A * 2.5 [∵ For fine sand, (k/A) = 0.50 m3/hr] ∴ A = 86.4 m2 We know that, A = ∏/4 * d2 86.4 = ∏/4 * d2 ∴ d = 10.49 m Related Posts:Needs of Traffic ForecastingSafe Yield, Secondary Yield And Design YieldDatabase Management System: Important TermsTypes of Environmental Audit And Its Importance Free 2024GSSSB Planning Assistant Study Materials (Class 3) Free 2024GSSSB Surveyor Study Materials (Class 3) Free 2024Factors Affecting PCUTopographic Map Definition, Features And Uses Free 2024Land Area Measurement And Units of Measurement Free 2024Isohyetal Method - 3 Methods To Calculate Average Rainfall FreeEnvironmental Pollution, Sources And Its Effects Free 2024TheodoliteTrap Efficiency, Density Currents And Capacity- Inflow RatioEnvironment Definition, Importance And Components Free 2024Indian Standard For Drinking Water (IS 10500 : 2012)PIEV Theory : 4 Easy ConceptsIntelligent Transport System And Its Advantages Free 2024Earthquake Management And Mitigation Free 20244 Types of Soil3160610 – Water Resources Engineering and Hydrology Study Materials, GTU Degree Civil…Environmental Impact Assessment (EIA) Process Free 2024Plane Table SurveyingElements of Map: Title, Scale, Grid, Key, Symbol Free 2024Difference Between Permeability And Transmissibility of SoilMap Scale, Classification, Types And Uses Free 2024
