Say you have a 3 inchs diameter tube and u have a machine that sucks air from it with force A. Then you have 2 tubes that is binded together each with a 1.5 inch diameter and have the same machine sucks air from it with force A also. Would the air velocity of the 3 inchs tube be slower, faster or equal to the 2 1.5 inch diameter tube?
