How to Calculate Head given Time Required to Lower Liquid Surface using Francis Formula?
Head given Time Required to Lower Liquid Surface using Francis Formula calculator uses Average Height of Downstream and Upstream = (((2*Cross-Sectional Area of Reservoir)/(1.84*Time Interval for Francis))*(1/sqrt(Head on Downstream of Weir)-1/sqrt(Head on Upstream of Weir))-Length of Weir Crest)/(-0.1*Number of End Contraction) to calculate the Average Height of Downstream and Upstream, Head given Time Required to Lower Liquid Surface using Francis Formula is specific measurement of liquid pressure above vertical datum. It is usually measured as liquid surface elevation. Average Height of Downstream and Upstream is denoted by HAvg symbol.
How to calculate Head given Time Required to Lower Liquid Surface using Francis Formula using this online calculator? To use this online calculator for Head given Time Required to Lower Liquid Surface using Francis Formula, enter Cross-Sectional Area of Reservoir (AR), Time Interval for Francis (tF), Head on Downstream of Weir (h2), Head on Upstream of Weir (HUpstream), Length of Weir Crest (Lw) & Number of End Contraction (n) and hit the calculate button. Here is how the Head given Time Required to Lower Liquid Surface using Francis Formula calculation can be explained with given input values -> 6.888243 = (((2*13)/(1.84*7.4))*(1/sqrt(5.1)-1/sqrt(10.1))-3)/(-0.1*4).
