Unformatted text preview: What net Force does this pressure di±erence produce on a rooF having an area oF 174 m 2 ? Answer in units oF N. 005 (part 1 oF 2) 10.0 points A liquid oF density 1286 kg / m 3 ²ows with speed 2 . 66 m / s into a pipe oF diameter 0 . 14 m . The diameter oF the pipe decreases to 0 . 05 m at its exit end. The exit end oF the pipe is 6 . 87 m lower than the entrance oF the pipe, and the pressure at the exit oF the pipe is 1 . 3 atm . P 1 2 . 66 m / s . 14 m P 2 v 2 . 05 m 1 . 3 atm 6 . 87 m What is the velocity v 2 oF the liquid ²owing out oF the exit end oF the pipe? Assume the viscosity oF the ²uid is negligible and the ²uid is incompressible. The acceleration oF gravity is 9 . 8 m / s 2 and P atm = 1 . 013 × 10 5 Pa. Answer in units oF m / s. 006 (part 2 oF 2) 10.0 points Applying Bernoulli’s principle, what is the pressure P 1 at the entrance end oF the pipe? Answer in units oF Pa....
