Hydroplaning
Just pondering about the difference between hydroplaning speeds when taking off and landing.
Landing: V=7.7*Square(PSI)
T/O: V=8.6*Square(PSI)
What I would like to know is why there is a difference from a physics point of view.
I see the difference as far as you are starting rolling with the tires on the pavement when you take off, and when landing you are first entering the water, and therefore the speed will be higher.
But if anyone could give me a detailed explanation or direct me to a webpage that explains it 100% I would be greatful.
