Hi, A chamber (manifold type cylinder) has 1 inlet and 8 outlets of 3 inch diameter each. 8 suction blowers are connected to the chamber's outlet. Each blower's suction flow rate is 1000 cfm. what will be the flow rate through the inlet of the chamber (diameter = 3 inches). Will the inlet flow rate reduce because of reduced cross section? What should be the chamber's inlet diameter to receive 4000, 6000 and 8000 cfm ?
