May 25, 2015 · Discharge coefficient calculation and data presentation This is another simple activity that allows one to demonstrate how to calculate the discharge coefficient for a simple orifice. This activity is used in our introductory fluid mechanics lab and is very cheap and easy to setup. The basic principle is that discharge is directly related to the water depth above the crotch (bottom) of the V; this distance is called head (h). The V-notch design causes small changes in discharge to have a large change in depth allowing more accurate head measurement than with a rectangular weir. Triangular Weir (V-Notch Weir) Equations Determine the maximum discharge over a broad-crested weir 60 meters long having 0.6 m height of water above its crest. Take coefficient of discharge as 0.595. Also determine the new discharge over the weir, considering the velocity of approach. The channel at the upstream side of the weir has a cross-sectional area of 45 sq meters. Here we can calculate for Orifice Flow Rate. ... Orifice Flow Rate: Flow Rate: Discharge Coefficient: Orifice Area: Gravitational Constant: Center Line Head: where, Q = Flow Rate, C d = Discharge Coefficient, A o = Orifice Area, g = Gravitational Constant, H = Center Line Head.

Determine the maximum discharge over a broad-crested weir 60 meters long having 0.6 m height of water above its crest. Take coefficient of discharge as 0.595. Also determine the new discharge over the weir, considering the velocity of approach. The channel at the upstream side of the weir has a cross-sectional area of 45 sq meters. The discharge through the orifice was determined by measuring the rate of change of the water level in the tank versus time. A water level versus volume drained calibration was used to find the rate of change of volume over time, and hence the discharge coefficient. The study determined that the discharge coefficient increased with decreasing 5. Discharge Through a Submerged Rectangular Orifice . The equation for computing the discharge of the standard submerged rectangular orifice is: (9-1b) where: Q = discharge (ft 3 /s) C c = coefficient of contraction C vf = coefficient of velocity caused by friction loss C va = coefficient to account for exclusion of approach velocity head from ...

Stage Discharge Calculations Outlet structure discharges are treated as a function of the water surface elevation in the pond. The reason you create your pond previously (Step 2) is to provide the program a range of elevations on which to calculate the discharge values.

WEIR EXPERIMENTS, COEFFICIENTS, AND FORMULAS. By ROBERT E. HOKTON. INTRODUCTION. DEFINITIONS OF TERMS. The word "weir" will be used to describe any structure used to determine the volume of flow of water from measurements of its depth on a crest or sill of known length and form. In this general The discharge coefficient characterises the relationship between flow rate and pressure loss based on the geometry of a nozzle or orifice. You can find typical values in our article on discharge coefficients for nozzles and orifices.

Discharge Coefficient Equation. Valid for 0.4 ≤ C ≤ 0.8 and 0.2 ≤ β ≤ 0.7. Derivation of Discharge Coefficient Equation. Steady flow of an incompressible fluid through an orifice based on a discharge coefficient: Pressure loss from location 1 to 3 in the pipe written in terms of discharge coefficient: for discharge coefficient available at present for that purpose. This leaves a few choices for architects in configuring building openings. Nattavut et al. [1-2] performed an experiment CALCULATION OF DISCHARGE COEFFICIENT IN COMPLEX OPENING (LAMINAR FLOW) If the flow meter is an orifice meter with one of the ISO standard pressure tap configurations, then the third Excel template can be used to calculate a value for the orifice discharge coefficient.
