the ground. The upstream air has a velocity of 10 mm/s, and the air in the down-
stream passageway is at atmospheric pressure.

Flow direction

10.5 Conduct fluid analysis of the air flow passing through an S-pipe. Assume nonslip
boundary conditions along the pipe walls and the air is at a room temperature of
25°C. The velocity of the air is 5 mm/s at the inlet and the outlet is at atmospheric
pressure. Determine the pressure and velocity distributions of the interior flow field.

All dimensions are in millimeters.

10.6 Conduct fluid analysis of the water flow passing through an orifice. Assume
nonslip boundary conditions on the walls. The water has a uniform velocity of
15 mm/s at the inlet and the outlet is at atmospheric pressure. Determine the
pressure and velocity distributions of the flow field.
