A university laboratory that generates 15 m3/s of air flow at design condition wishes to build a wind tunnel with variable speeds. It is proposed to build the tunnel with a sequence of three circular test sections: section 1 will have a diameter of 1.5 m, section 2 a diameter of 1 m, and section 3 a diameter such that the average speed is 75 m/s.
(a) What will be the speeds in sections 1 and 2?
(b) What must the diameter of section 3 be to attain the desired speed at design condition?
