Question

A water pipe tapers down from an initial radius of R1 = 0.23 m to a final radius of R2 = 0.08 m. The water flows at a velocity v1 = 0.83 m/s in the larger section of pipe.

Using this water supply, how long would it take to fill up a
swimming pool with a volume of V = 153 m^{3}? (give your
answer in minutes)

4)

The water pressure in the center of the larger section of the
pipe is P_{1} = 263380 Pa. Assume the density of water is
10^{3} kg/m^{3}.

What is the pressure in the center of the smaller section of the pipe?

Answer #1

A water pipe tapers down from an initial radius of R1
= 0.2 m to a final radius of R2 = 0.09 m. The water
flows at a velocity v1 = 0.86 m/s in the larger section
of pipe.

water flows steadily from the left pipe section (radius
r1 = 2.00R), through the middle
section (radius R = 0.0106 m), and into the right section
(radius r3 = 3.00R). The speed of the
water in the middle section is 0.402 m/s. What is the net work done
on 0.310 m3 of the water as it moves from the left to
the right section?

Water is flowing into a factory in a horizontal pipe with a
radius of 0.0163 m at ground level. This pipe is then connected to
another horizontal pipe with a radius of 0.0380 m on a floor of the
factory that is 11.6 m higher. The connection is made with a
vertical section of pipe and an expansion joint. Determine the
volume flow rate that will keep the pressure in the two horizontal
pipes the same.

An ideal fluid of density 0.9 X 103 kg/m3 flows through a level
pipe with radius 0.5 cm at a velocity of 6 m/s, the pressure in the
fluid is 1.3 X 105 N/m2. This pipe connects to a second pipe also
level and with a radius of 1.5 cm into which the fluid continues.
(a) What is the velocity in the larger pipe? (b) What is the
pressure in the larger radius pipe?

Water, with a density of ρ = 1155 kg/m3, flows in a horizontal
pipe. In one segment of the pipe the flow speed is v1 = 7.73 m/s.
In a second segment the flow speed is v2 = 1.57 m/s. What is the
difference between the pressure in the second segment (P2) and the
pressure in the first segment (P1) ?

A horizontal pipe widens from a radius of 0.120 m to 0.260 m. If
the speed of the water is 2.00 m/s in the smaller pipe, what is the
speed in the larger pipe (in m/s)?

Water moves through a constricted pipe in steady, ideal flow. At
the lower point shown in the figure below, the pressure is 1.65 ✕
105 Pa and the pipe radius is 2.80 cm. At the higher point located
at y = 2.50 m, the pressure is 1.27 ✕ 105 Pa and the pipe radius is
1.30 cm. (a) Find the speed of flow in the lower section. m/s (b)
