Coefficient of Discharge for Free Flow Sluice Gates
Journal of King Saud University: Engineering Sciences, 1999 This paper aims to investigate the effect of sill shape located under the sluice gate on the coefficient of discharge for free gate flow conditions. Both sill shape and sill height are studied. Shapes tested include both polygonal and non polygonal sills.

Discharge Coefficient of Contracted Rectangular Sharp-Crested Weirs, an Experimental Study
Journal of Engineering, 2023 An experimental study is made here to investigate the discharge coefficient for contracted rectangular Sharp crested weirs. Three Models are used, each with different weir width to flume width ratios (0.333, 0.5, and 0.666).

Coefficient of Discharge of the Piston Valve
Transactions of the Japan Society of Mechanical Engineers, 1954 By the use of oil, the present authors have determined the coefficients of discharge, C, of the piston valves with a single hole, and have obtained an experimental formula, where C is represented as a function of hole diameter, d (mm), and of opening ratio of the hole, m.

Discharge Coefficient for Cylindrical Weirs
Tikrit Journal of Engineering Sciences, 2006 The hydraulic characteristics of cylindrical weirs under free flow conditions were studied experimentally in order to investigate the discharge coefficient (Cd) and the influence of some significant factors and performance of weirs for discharge measuring. The experimental tests were carried out on three models of weirs in which the diameter of weir (D)
