write my assignment 228

A liquid of density 1230 kg/m3 flows withspeed 1.43 m/s into a pipe of diameter 0.1 m.The diameter of the pipe decreases to 0.05 mat its exit end. The exit end of the pipe is8.03 m lower than the entrance of the pipe,and the pressure at the exit of the pipe is1.5 atm.What is the velocity v2 of the liquid flowingout of the exit end of the pipe? Assume theviscosity of the fluid is negligible and the fluidis incompressible. The acceleration of gravityis 9.8 m/s2 and Patm = 1.013 × 105 Pa.Answer in units of m/s. Applying Bernoulli’s principle, what is thepressure P1 at the entrance end of the pipe?Answer in units of Pa.
