Seek help with unit conversion for saturated steam flow rate
Thread Content
The flow rate displayed by the flow meter is the volumetric flow rate in m3/h, while the DCS shows the mass flow rate in T/H. If the flow rate indicated is 1000 m3/h, what is the corresponding value in T/H?
m = MxV/Vm, where M is the relative molecular mass of the steam, V is the volume flow rate, and Vm is the standard molar volume! m=18x1000/22.4=803.57kg/h=0.8t/h
The density is calculated from the measured actual temperature and pressure, using a density table.
If it is determined to be saturated, it is either the temperature or the pressure.
The density of saturated steam is set as p; the mass flow rate (T/H) = 1000 x P / 1000. All one needs to do is know the temperature and pressure of the saturated steam, and the corresponding density p can be found by searching online
What on earth are these 1000p/1000?
I wonder how the original poster managed to finish middle school; could one start working in instrumentation right after finishing elementary school?
It shows that 1000 m3/h multiplied by the density of saturated steam (kg/m3) equals 1000 pkg/h; by dividing by 1000, this value is converted to t/h
In the case of saturated steam, the corresponding steam density is found using a table based on the current pressure or temperature; this value is then multiplied by m3 to obtain t/h
