Dear All,

I have a pipe. Given that they have symmetry plane. I will only model half of it. (Sacrifice some accuracy).

I wish to inject particle at second inlet. However, I am quite confused with how the mass flow rate and velocity works.

I know continuity equation said that mass_flow_rate = densityxvelocityxarea =pAv = m_dot

or m_dot = p_v_dot(volume_flow_rate)
Let said I want to introduce 1 litre/min (1x10-3/60)
Let say my density of fluid is 1000 m^3/kg

Then will give me mass_flow of =0.0166 kg/s right?

For a given area let say my pipe is symmetry which means my injection will be (half circle area), if I *tick* scale with area. Which means the flow rate will be double? Since I apply symmetry instead of full circle area.

how about the velocity? The problem is droplet is not a continuum. how I work it out with the pAv formula?

Can someone explain to me slightly so I can apply right flow rate to my system.

Thanks

Kind Regards,
Jee
