Estimate the percentage change in the test section air speed

One of the problems of wind tunnel testing at airspeeds near sonic speed is the large effect on the flow conditions of a small change in the test configuration. Suppose sonic velocity in a wind tunnel with a 10 ft2 test section cross section is 1000 ft/s. Estimate the percentage change in the test section air speed when a model of 0.1 ft2 cross section is placed in the test section, if the air speed in the empty tunnel is 100, 900 and 1100 ft/s.
