Every few years, winds in Boulder, Colorado, attain sustained speeds of 43.0 m/s (about 100 mph) when jet steam descends during early spring. Approximately what is the force due to the Bernoulli equation on a roof having an area of 220m2? Typical air density in Boulder is 1.14kg/m3, and be corresponding atmospheric pressure is 8.89104 N/m2. (Bernoulli’s principal as stated in the text assumes laminar flow. Using the principle here produces only an approximate result, because there is significant turbulence.)

A sump pump (used to drain water from be basement of houses built below the water table) is draining a flooded basement at rate of 0.750 L/S, with an output pressure of 3.00105N/m2 . (a) The water enters a hose with a 3.00-cm inside diameter and rises 2.50 m above the pump. What is its pressure at this point? (b) The hose goes over the foundation wall, losing 0.500 m in height and widens to 4.00 cm in diameter. What is the pressure now? You may neglect frictional losses both parts of the problem.
An oil gusher shoots crude 25.0 m the through a pipe with a 0.100-m diameter. Neglecting resistance but not resistance of the pipe, and assuming laminar flow, calculate pressure at be entrance of be 50.0-m-Iong vertical pipe. Take of the oil to be 900 kg/m3 and its viscosity to be 100(N/m2) s (or 1.00 Pa s). Note that you must take into account the pressure due to 50.0-m column of oil in pipe.
