Answer all 3 questions
Show all assumptions, equations, and working.
Question 1
a) (5 pts) Consider the flow in a clamped, horizontal pipe shown in Fig 1. Draw a suitable
control volume for this problem.
Use the equations for conservation of mass and momentum in integral form.
b) (5pts) Assume the flow through the pipe is steady, inviscid, incompressible, and body
forces are only due to gravity. Show how the mass and momentum conservation
equations are simplified with these assumptions.
c) (5pts) Assume the flow properties are uniform across the inlet and outlet. The fluid
enters the channel with velocity V

. Apply the equations in b) to solve for the fluid
velocity at the outlet of the pipe.
d) (15pts) The fluid exerts a constant pressure p

over surface B, the face of the
contraction. Solve for the horizontal
