I can match either one it does not matter on my end. The mass flow rate into the 602 mm^2 inlet area is 0.00000581 kg/s. If there is a way to scale it and match this same flow for the 402 mm^2 thats fine. Either mass flow or velocity both would be fine as long as I can scale it correct so both surface areas are producing the same inlet flow into the domain. Thank you for your reply Rob!
