A model airplane has a wing span of 6 ft and a chord (leading edgetrailing edge distance)
Question:
A model airplane has a wing span of 6 ft and a chord (leading edge–trailing edge distance) of 4.5 in. The model flies in air at 60°F and atmospheric pressure. The wing can be regarded as a flat plate so far as drag is concerned.
(a) At what speed will a turbulent boundary layer start to develop on the wing?
(b) What will be the total drag force on the wing just before turbulence appears?

I have been a tutor for the past 5 years. I have experience working with students in a variety of subject areas, including computer science, math, science, English, and history. I have also worked with students of all ages, from elementary school to college. In addition to my tutoring experience, I have a degree in education from a top university. This has given me a strong foundation in child development and learning theories, which I use to inform my tutoring practices.
I am patient and adaptable, and I work to create a positive and supportive learning environment for my students. I believe that all students have the ability to succeed, and it is my job to help them find and develop their strengths. I am confident in my ability to tutor students and help them achieve their academic goals.
