WebThe discharge coefficient is a dimensionless number used to characterise the flow and pressure loss behaviour of nozzles and orifices in fluid systems. Orifices and nozzles are typically used to deliberately reduce … WebThe standard primary flow sensors commonly used in differential pressure flow meters are the orifice plates, flow nozzles and venturi tubes. These flow meters are often called "head loss" meters because there is a …
WebJan 1, 1971 · The coefficient for an orifice plate is about 0.6, lower than for a venturi, while the permanent head loss is normally 60% to 70% of the differential pressure. This … WebOct 31, 2024 · β = ratio of pipe diameter to orifice diameter (d 1 /d 2) The volume flow rate at the orifice plate can then be expressed as: Where: A 2 = flow cross-section area at the orifice plate (m 2) Pressure loss due to orifice plate. In reality, there is always some pressure loss due to frictional effects when fluid passes through orifice plates.
