Using data from part 1, plot a log-log graph of pressure drop (Ap) vs air flow, with a separate curve for each water flow. Comment on the shape of the curves. They should be straight and parallel. Are they? How straight? How parallel? What do graphs prove? Make your comments specific.

Q3- Calculate the thickness of the boundary layer at a distance of 75 mm from the leading edge of a plane surface over which water is flowing at a rate of 3mls. Assume that the flow in the boundary layer is streamline

Calculate the viscosity of oxygen at 350 K and 1 atm pressure using equation 7.12 on page 90 of the text (also found in the PowerPoint slides).and compare with the value in Appendix I.
