3:27 About side holes. Isn't the same as blowing air to hole of perpendicular tube ? Such blowing also should decrease pressure in side holes. Thank you for the sharing knowledge.
No, side holes is to measure static pressure in a fluid stream. Perpendicular hole measures velocity pressure. A pitot tube is a shell and tube device. Perpendicular hole is common to the inner tube and perpendicular holes are common to the outer shell or tube.

Yes, it is, but rotating the tube sideways to measure the static pressure is usually not feasible or not practical.

Parece ser bom! Pena que é em inglês!
