A low speed wind tunnel has a contraction ratio of 14:1 and the cross-sectional area of the test
section is 1 m2. The static pressure difference between the settling chamber and the test section is
40 cm of water column. Assume g=9.81 m/s2, ρair=1.2 kg/m3 and ρwater=1000 kg/m3. The
speed of air in the test section (in m/s) is
