2. [0/2 Points] DETAILS PREVIOUS ANSWERS OSCOLPHYS1 12.1.013. Water is moving at a velocity of 2.50 m/s through a hose with an internal diameter of 1.60 cm. (a) What is the flow rate in liters per second? 0.393 L/s (b) Fluid velocity in this hose's nozzle is 16.0 m/s. What is the nozzle's inside diameter? 1.414 cm Submit Answer 3. [0/1 Points] DETAILS PREVIOUS ANSWERS OSCOLPHYS1 12.2.021. MY NOTES ASK YOUR TEACHER MY NOTES ASK YOUR TEACHER 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 230 m? Typical air density in Boulder is 1.14 kg/m, and the corresponding atmospheric pressure is 8.89 104 N/m. (Bernoulli's principle as stated in the text assumes laminar flow. Using the principle here produces only an approximate result, because there is significant turbulence.) -276285 N 2.
