Question

A liquid of density 1193 kg/m3
flows with
speed 1.92 m/s into a pipe of diameter 0.26 m .
The diameter of the pipe decreases to 0.05 m
at its exit end. The exit end of the pipe is
7.58 m lower than the entrance of the pipe,
and the pressure at the exit of the pipe is
1.3 atm.What is the velocity v2 of the liquid flowing
out of the exit end of the pipe? Assume the
viscosity of the fluid is negligible and the fluid
is incompressible. The acceleration of gravity
is 9.8 m/s 2 and Patm = 1.013 × 105Pa.Answer in units of m/s
