Question
1)A spherical balloon has a radius of 6.60 m, and is filled with helium. How large a cargo can it lift, assuming that the skin and structure of the balloon have a mass of 930 kg? Neglect the bouyant force on the cargo volume itself.2) What is the lift (in newtons) due to Bernoulli's principle on a wing of area 72.4 m2 if the air passes over the top and bottom surfaces at speeds of 273 m/s and 169 m/s, respectively?
3) An arteriole has a length of 1.03 mm and a radius of 24.7 %u03BCm. The blood pressure drop along the arteriole is 1690 Pa.
Calculate the resistance of the arteriole. (assume body temperature)
Calculate the flow rate through the arteriole.
