hi do I just use Bernoulli principle to solve? or do I have to solve for -D first could someone help and explain why please.

Every few years, winds in Boulder, Colorado, attain sustained speeds of 45.0 m/s (about 100 miles per hour) when the jet stream descends during early spring. Approximately what is the force due to the Bernoulli effect on a roof having an area of 245 m2? Typical air density in Boulder is 1.14 kg/m3, and the corresponding atmospheric pressure is 8.89 ✕ 104 N/m2. (Bernoulli's principle as stated in the text assumes laminar flow. Using the principle here produces only an...
hi could someone assistant with this problem? Do I use F/A =mg/A? Do I need to find the area first. how do I solve. Could I get help with part a and b. 16) As a person walks, their entire weight is momentarily placed on one heel of their shoes. a) Calculate the pressure in Pascals exerted on the floor by the heel if the person is walking in stiletto heels. Assume the heels have a circular cross section with...
