Step 1

To calculate the pressure difference, we subtract the initial pressure (P0) from the measured pressure (P). ΔP = P - P0 Using the given data, we can calculate the pressure difference for each data point: ΔP = [6.34, 6.28, 6.06, 5.72, 5.1, 4.78, 4.37, 3.89, Show more…

The resistance force acting on the disc required for the pressure difference formed on a circular disk with a diameter of 0.5 m held against the air flow is calculated so that the error order is not less than h ^ 4. r(m) P (kN/m2) 6.34 6.28 6.06 5.72 5.1 4.78 4.37 3.89 3.41 2.74 0.78 0 0.05 0.1 0.15 0.2 0.25 0.3 0.35 0.4 0.45 0.5
