Hi guys i've been reading on the boards for a few days now and everyone here seems really helpful, so i've decided to come and ask for some guidence on a problem i've been having 1. The problem statement, all variables and given/known data I have to find the terminal velocity of a smooth wooden ball. rho(ball)=420 kg/m^3 rho(air)=1.1614kg/m^3 mu=1.846x10^-5 N-s/m^2 dia(ball)=.2m 2. Relevant equations I am given a table of about 25 reynolds numbers and drag coeff values, i can post them if it is necessary 3. The attempt at a solution My approach was to use the terminal velocity equation mg=(.5)(rho of ball)(v)^2(A)(drag coeff) to guess a value for the velocity, then calculate the drag coeff, then use my guessed velocity to calculate reynolds number using Re=[(rho ball)(v)(dia ball)]/mu Then my plan was to take my calculated reynolds number(which i hoped was the same as one of the reynolds numbers in my given table) and then take the corresponding drag coeff and see if it matched my calulated drag coeff, and if it i would know that the guess i made for the terminal velocity was correct. But i cannot get this approach to work, my calulated Re values are much larger than my table values. Any suggestions?
