Does orifice size affect flow rate
WebA variety of factors affect droplet size and how easily a stream of liquid atomizes after emerging from an orifice. Among these factors are fluid properties of surface tension, viscosity, and density. ... The operator can regulate the flow rate of fluid independently of the energy source.

WebSuperheated Steam Relief Valve Sizing. Description: A safety relief valve must be sized for superheated steam in a large vessel at a set pressure of 110.4 barg for a mass flow rate of 69800 kg/hr, assuming 10% overpressure.The temperature of the steam is 420 o C, the discharge coefficient is 0.84 and the back-pressure capacity correction coefficient is 1.0. An orifice plate is a thin plate with a hole in it, which is usually placed in a pipe. When a fluid (whether liquid or gaseous) passes through the orifice, its pressure builds up slightly upstream of the orifice but as the fluid is forced to converge to pass through the hole, the velocity increases and the fluid pressure decreases. A little downstream of the orifice the flow reaches its point of maximum convergence, the vena contracta (see drawing to the right) where the velocity reache…
