For the experimental set-up of Fig P7.20, suppose the stream velocity is unknown and the pitot stagnation

Question:

For the experimental set-up of Fig P7.20, suppose the stream velocity is unknown and the pitot stagnation tube is traversed across the boundary layer of air at 1 atm and 20°C. The manometer fluid is Merriam red oil, and the following readings are made:
y, mm: 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0
h, mm: 1.2 4.6 9.8 15.8 21.2 25.3 27.8 29.0 29.7 29.7
Using this data only (not the Blasius theory) estimate
(a) The stream velocity,
(b) The boundary layer thickness,
(c) The wall shear stress, and
(d) The total friction drag between the leading edge and the position of the Pitot tube.
