Engineering ToolBox - Resources, Tools and Basic Information for Engineering and Design of Technical Applications! Steam flow through orifices - for steam pressures ranging 2 - 300 psi
Steam flow rates can be measured by using orifice plates. The diagram below indicates steam flow rate
(lb through orifices ranging diameter s/hr) 1/32" to 1/2" and 2 - 300 psig steam line pressure.
Downstream pressure equals atmospheric pressure.
1 lb/hr = 1.26x10 -4 kg/s 1 psi (lb/in 2) = 6,894.8 Pa (N/m 2) = 6.895x10 -3 N/mm 2 = 6.895x10 -2 bar convert inch to mm Example - Steam Flow through a 1/4" orifice discharging to the atmosphere - steam pressure 50 psi
By drawing the lines as in the chart above - the discharged steam flow can be estimated to
