Question

1. Water moves through a pipe with a cross-section area of 4.20 m^2 at speed of 2.25m/s with pressure P1 of 1.65x 10^5 Pa. If the cross section area at p2 is 1.80m^2 and the water has traveled up a distance of y=3.30 m, what is the pressure P2?

2. A 2.50 cm diameter piston pushes on an incompressible liquid with force F1. An object with a mass of 1.80x10^3kg sets on the second piston with a diameter of 3.20m. Find the force F1 to lift the mass?

Answer #1

Water is moving with a speed of 4.6 m/s through a pipe with a
cross-sectional area of 3.5 cm2. The water gradually descends 8 m
as the pipe increases in area to 8.3 cm2.
(a) What is the speed at the lower level? m/s
(b) If the pressure at the upper level is 1.7 ✕ 105 Pa, what is
the pressure at the lower level? Pa

Water is flowing at 5.00 m/s in a pipe where the cross section
is 4.00 cm2 and the pressure is 1.5 x 105 Pa. If the area gradually
becomes 8.00 cm2 at a point 10.0 m below the first point, find the
pressure at the second point.

Water is flowing in a straight horizontal pipe of variable cross
section. Where the cross-sectional area of the pipe is 2.90·10-2
m2, the pressure is 10.90·105 Pa and the velocity is 0.310 m/s. In
