The rectangular weir is the most commonly used thin plate weir. Weirs are typically installed in open channels such as streams to determine discharge (flowrate). The basic principle is that discharge is directly related to the water depth (h) in the figure above h is known as the "head."

Live Chatc d = discharge coefficient . The discharge coefficient depends on different parameters such as upstream and tailwater depths, gate opening, contraction coefficient of the gate and the flow condition. In practice the typical discharge coefficient is approximately 0.61 for free flow conditions and depth ratios h o / h 1 < 0.2. Sluice Gate

Live ChatIn a nozzle or other constriction, the discharge coefficient (also known as coefficient of discharge) is the ratio of the actual discharge to the theoretical discharge, i.e., the ratio of the mass flow rate at the discharge end of the nozzle to that of an ideal nozzle which expands an identical working fluid from the same initial conditions to the same exit pressures.

Live ChatThis hole or opening is called an orifice, so long as the level of the liquid on the upstream side is above the top of the orifice. The typical purpose of an orifice is the measurement of discharge. An orifice may be provided in the vertical side of a vessel or in the base. But the former one is more common.

Live Chatcalculating the discharge coefficient in complex opening by adding more types of complex opening as well as more air flow directions to equations to determine the discharge coefficient through opening. The rectangular, square and CALCULATION OF DISCHARGE COEFFICIENT IN COMPLEX OPENING (LAMINAR FLOW)

Live ChatGravity discharge of freeflowing (noncohesive) solids, such as dry sand or plastic pellets, out of a vessel is a common practice. The discharge rate is usually throttled by altering the opening of an orifice the maximum discharge rate is obtained when the outlet is fully open.

Live Chatmassflow discharge pattern should be selected. If a massflow bin is required based on the flow characteristics of the powder or bulk solids, the next step is to determine an appropriate outlet size and feeder. Keep in mind that the massflow bin design process is iterative. The actual outlet size will depend on the required discharge rate
