Velocity =100m/s
The MFile function changes for velocity of 100m/s as the Reynolds number is
out of range, because of this it was assumed that for Reynolds greater than
400000 c and m would be 0.027 and 0.805 respectively.(Re range for
40,000-400,000) as
Answer for question 4a
Base on the MFile Function written the user will be prompted to enter the velocity and diameter
given in the question.
