A wind tunnel has an incompressible flow of air, flowing horizontally from an inlet section, 7 times the test section. A u-tube is connected, having mercury inside. The mercury's specific weight is 1.33x10^5 N/m^3. Air condition at the inlet section is 1 atm and 280K respectively. Solve for the change in height inside the mercury if the velocity at the throat is 70m/s.
