flow rate query.
flow rate query.
(OP)
I am trying to design a oil water separator and need to figure out a worst case concentration for a spill of 20,000 gallons of No. 6 oil say within a time of 4 hours. This is mixed with a peak flow of 7.5 MGD. I was able to do the following:
20000 gallons/hour = 5000 gallons/hour and 7.5 MGD is almost 100,000 gallons/hour.
To calculate the concentration in ppmv :
(5000/105000)*10^6 = 47620 ppmv.
How can I convert this above value into mg/l or a mass based flow rate.
Other information. Specific Gravity of No.6 oil = 0.98.
Density of Wastewater = 980 kg/m3.
Any help is appreciated or any texts that can be of use will also be useful.
Thanks in advance.

RE: flow rate query.
That mistake should be pretty easy for an engineer to catch himself and the rest is just multiplying the numbers you already have.
Are you doing homework here, or what?

RE: flow rate query.
Can someone give me some information on volumetric flow rates and mass flow rates when it involves wastewater.
I think it is possible to calculate the concentration of air using temperature, pressure and molecular weight. Is there a similar relation for flow rates for wastewater.
thanks...
RE: flow rate query.
or
Mass flowrate = Volumetric flowrate * SG * Density of water.
Density of Water = 62.4 pcf
