jpo Member Join Date: Apr 2009 Posts: 94 Rep Power: 17	Dear All, I have to guess the static pressure at pressure outlet - it has to produce (approximately) my desired mass flow rate. I know the following: - the area of the outlet - the target mass flow rate - air density can be approximated to be 1.2 kg/m^3 - from above three quantities, I can calculate air velocity through the outlet Outlet is open to the atmosphere. My operating pressure is set to zero. How do I guess the static pressure at the pressure outlet?
