Formula The Francis equation is as follows q = ×( b ×h ) ×h3/2 Where, q = Flow Rate b = Width of the h = Head on the . The discharge rates of open channels such as streams can be measured using this rectangular calculator.
Aug 08, 2010· Discharge coefficients for water flow through a vertical, circular orifice at the bottom of a conical hopper were experimentally studied in the present paper. The conical hopper consists of a cylindrical hopper of inside diameter of 48 cm and a bottom cone of side slope of 45°.
DESIGN AND APPLICATION OF FEEDERS FOR THE CONTROLLED LOADING OF BULK SOLIDS ... the type of discharge flow pattern and maximum potential rate of discharge. Figure 1 Hopper/Feeder combinations for loading conveyor belts ii. Feeder The feeder controls and meters the flow of bulk material from the hopper to meet the specified discharge flow ...
where, m ̇ is the discharge rate, C is a discharge rate constant having value for most of the materials, ρ is the bulk density, D is the outlet diameter of hopper, k is a shape factor having value for spherical particles and d is the particle diameter. This equation was found to give a good estimate of mass discharge rate for cylindrical hopper assembly having circular outlet.
Diameter, Velocity and Flow Rate Calculator. The following formula is used by this calculator to populate the value for the flow rate, pipe diameter or water velocity, whichever is unknown: V = × Q/D2 V = Water Velocity; Q = Flow Rate; D = Pipe Diameter.
By utilizing a longer feeder, the discharge opening of the hopper was extended back into the previous dead zone, creating a rectangular outlet and, in the process, significantly increasing the live area. At the same time, the feed rate to the impactor was uprated, thereby increasing operational productivity.
• A minimum of 25 points must be measured in a rectangular duct traverse. • When traversing a duct side less than 18 in. (450 mm), take readings from the center of equal areas that are no more than 6 in. (150 mm) apart, with a minimum of two points per side of the duct.
Volume of a Rectangular Hopper Calculator | Rectangular ... Volume of a Rectangular Hopper Calculator. Hoppers are most commonly used in the industrial and farming fields. A tapered hopper is generally in the shape of a pyramid or cone which is turned upside down with a large top that tapers down to a smaller bottom.

Orifice flow meter calculator solving for discharge coefficient given flow rate, orifice area, gravitational constant and center line head Orifice Flow Meter Equations Formulas Design Calculator Discharge .
Results indicate that the discharge rates for almost all the spherical materials in the 110 hopper differ ed from those in the flatbottomed one by less than 5%. On the other hand, discharge ra tes in the 110 hopper for most of the nonsphericals differed by around 10% when co .
For example, particle size and hopper width are shown to have a minimal influence on the discharge rate. In addition, for rectangular hoppers, the discharge rate is shown to vary with the outlet ...
The width of the rectangular slot. The default value is 1e2 m. Flow discharge coefficient. Semiempirical parameter for orifice capacity characterization. Its value depends on the geometrical properties of the orifice, and usually is provided in textbooks or manufacturer data sheets. The default value is Initial opening. Orifice initial opening.
The Manning formula uses water surface slope, crosssectional area, and wetted perimeter of a length of uniform channel to determine the flow rate. The crosssection area (A) and the hydraulic radius (R) are calculated for the given depth of the liquid in the channel at the moment of measurement (and not at some arbitrary maximum or minimum condition).
particles have settled and come to rest, the hopper outlet is opened. Discharge rate of particles with time is studied. Figure 1: Rectangular flat bottomed hopper used in discharge study. Figure 2 shows DEM simulation snapshots of hopper filling and discharge. Particles are fed into the
May 16, 2015· You can find the flow rate via the following equation provided you can either approximate the discharge coefficient or determine it otherwise. Sources I can reference suggest that a welldrilled, clean and smooth orifice can be approximated with a discharge coefficient of to, for example.
Discharge (flow rate) can be computed for water flowing out of a circular culvert that is up to half full. The end depth method is based on the International Organization of Standards publication 4371 dated 1984 . Knowing the culvert diameter and the depth of flow where the water drops off ( at the end of the culvert), the discharge can be computed.
means by which the rate of solids flow from a bin or hopper is controlled. When a feeder stops, solids flow should cease. When a feeder is turned on, there should be a close correlation between its speed of operation and the rate of discharge of the bulk solid. Feeders differ from conveyors in that the latter are only capable of transporting ...
