Calculation of solid content in gas-solid mixture
Thread Content
It is a certain gas-solid mixture with a flow rate under standard conditions of 400 Nm3/h and a flow rate under operating conditions of 175 m3/h; the solid content is 5%, and it operates for 5 hours per day. What is the mass of solids produced per day? Should the calculation be based on the operating condition flow rate or the standard condition flow rate?
May I ask, is the solid content value you provided based on standard operating conditions, or is it a value from actual operating conditions?
The value given in the table is “400 Nm3/h (solid content 5%)”. This should represent standard conditions, right?
So, since it’s under standard conditions, the calculated value represents the amount of solid under those conditions; in reality, it’s necessary to determine this through sampling and analysis! Calculating more is used when sampling for analysis is not possible.
Is it the direct volumetric flow rate of 400 multiplied by the solid content of 5%? Isn’t the solid content the mass fraction?
It’s given as a volume fraction, right? After you calculate it, you need to multiply by the density to get the mass!
