Flow Over A Barn 10 Pts A 50 M Long Storage Barn Is To Be Built With 7 Sides As Per The Cross Section Shown In The Fig 1 (95.51 KiB) Viewed 37 times

Flow over a barn (10 pts) A 50-m long storage barn is to be built with 7 sides as per the cross-section shown in the figure below. The dimension D = 5 m for each panel. Wind tunnel testing is performed on a 1:100 scale model to measure the average external pressure, pi on each panel (pint is the internal pressure). The tunnel wind speed is 10 m/s perpendicular to the long side. The results of the experimental measurements are listed below. P1 = 1.05 kPa P2 = 0.46 kPa P3 = -0.15 kPa P4 = -0.40 kPa P5 = -0.18 kPa P6 = 0.28 kPa P7 = 0.51 kPa Boundary layer effects are negligible. Other standard assumptions apply. Calculate the drag coefficient, CD. Clearly show all steps and simplifications. The numerical answer for CD is worth 1-pt whereas the method is worth 9-pts.
