1. Hi All
I had a quiz in my fluid mechanics class with the question
A ship model scale 1/25 is towed through seawater at a speed of 1m/s. A force of 2N is required to tow the model.
Find the speed of the ship if the prototype is subjected to wave resistance only.
2. REm=REp
CD=F/.5ρV^2A
RE=ρVD/μ
3. My attempt was comparing the two Reynolds numbers and solving for the velocity
my professor marked me wrong and said "Cannot match the RE numbers"
Any guidance is appreciated
