A liquid of density 1364 kg/m3 ows with speed 2.48 m/ s into a pipe of diameter 0.17 m. The diameter of the pipe decreases to 0.05 In at its exit end. The exit end of the pipe is 7.46 m lower than the entrance of the pipe, and the pressure at the exit of the pipe is 1.2 atm. 0.05 In Ql What is the velocity '02 of the liquid owirg out of the exit end of the pipe? Assume the viscosity of the uid is negligible and the uid is incompressible. The acceleration of gravity is 9.8 m/s2 and PM = 1.013 x 105 Pa. Answer in units of m / s. 021 (part 2 of 2) 10.0 points Applying Bernoulli's principle, what is the pressure P1 at the entrance end of the pipe? Answer in units of Pa. When a person inhales, air moves down the bronchus (windpipe) at 16.7cm/s. The average ow speed of the air doubles through a constriction in the bronchus. Assuming incompressible ow, and neglecting changes in height, determine the pressure drop in the constriction. The density of air is 1.29kg/m3. Answer in units of Pa
