The inlet diameter D for the pipe contraction show is 40 cm. Water at 20° C is flowing in the pipe. Ignore gravity. The inlet pressure at A is 120 kPa gage. It is observed that when the flow rate is 0.17 m³/s, cavitation takes place in the contraction. Under these conditions, what should be the diameter d?

To determine the velocity, we can use the Bernoulli's equation, which states that the sum of the pressure energy, kinetic energy, and potential energy per unit volume of a fluid remains constant along a streamline. Since we are ignoring gravity, the potential Show moreā¦

The 3.0 -cm-diameter water line in Figure $\mathrm{P} 13.40$ splits into two 1.0 -cm-diameter pipes. All pipes are circular and at the same elevation. At point $\mathrm{A}$, the water speed is $2.0 \mathrm{m} / \mathrm{s}$ and the gauge pressure is $50 \mathrm{kPa}$. What is the gauge pressure at point B?
Water flows at $0.25 \mathrm{L} / \mathrm{s}$ through a $10-\mathrm{m}$ -long garden hose $2.5 \mathrm{cm}$ in diameter that is lying flat on the ground. The temperature of the water is $20^{\circ} \mathrm{C} .$ What is the gauge pressure of the water where it enters the hose?
A 6.2 cm diameter pipe gradually narrows to 4.0 cm. When water flows through this pipe at a certain rate, the gauge pressure in these two sections is 35.0 kPa and 24.0 kPa, respectively. What is the volume rate of flow?
