Chow discharge coefficient
WebThis paper presents a graphical procedure for determining the formation constants of an artesian aquifer from pumping test data. The procedure is based on the principle that the coefficient of transmissibility is determined by the ratio of the drawdown to its rate of change with respect to the logarithm of the time since pumping started, or s/(δ s/δ … WebMar 1, 2016 · The experiment was carried out in the open channel Laboratory by using hydraulic bench, It was seen that, discharge coefficient varies indirectly with actual discharge. Chezy's constant is...

WebThe study determined that the discharge coefficient increased with decreasing head values. The study also found that the discharge coefficient decreased as the height above the floor was increased, up to a certain point. Another factor found to affect the discharge coefficient was the orifice diameter to riser diameter, or dD ratio.
