Air at past a Hat plate as in Fig. P4-4. A pitot stagna- tion tube, placed 2 mm from the wall, develops a water manometer head h = 21 mm. Use this information with the Blasius solution, Table 4-1, to estimate the position x of the pitot tube. Check to see if the flow is laminar.

And a reynolds number of  1.09 * 10^5

 

Just want to confirm my math

44. Air at 20°C and 1 atm flows past a smooth flat plate as in Fig. P4-4. A pitot stagna- tion tube, placed 2 mm from the wall, develops a water manometer head h = 21 mm. Use this information with the Blasius solution, Table 4-1, to estimate the position x of the pitot tube. Check to see if the flow is laminar. 20 m/s -X- Boundary layer 2 mm U + FIGURE P4-4
