Q: Water moves through a constricted pipe in steady, ideal flow.

Water moves through a constricted pipe in steady, ideal flow. At the lower point shown in Figure P9.42, the pressure is 1.75 x 105 Pa and the pipe radius is 3.00 cm. At the higher point located at y =...

Q: A jet of water squirts out horizontally from a hole near the

A jet of water squirts out horizontally from a hole near the bottom of the tank shown in Figure P9.43. If the hole has a diameter of 3.50 mm, what is the height h of the water level in the tank? Figu...

Q: A large storage tank, open to the atmosphere at the top

A large storage tank, open to the atmosphere at the top and filled with water, develops a small hole in its side at a point 16.0 m below the water level. If the rate of flow from the leak is 2.50 x 10...

Q: The inside diameters of the larger portions of the horizontal pipe depicted

The inside diameters of the larger portions of the horizontal pipe depicted in Figure P9.45 are 2.50 cm. Water flows to the right at a rate of 1.80 x 10-4 m3/s. Determine the inside diameter of the co...

Water is pumped through a pipe of diameter 15.0 cm from the Colorado River up to Grand Canyon Village, on the rim of the canyon. The river is at 564 m elevation and the village is at 2096 m. (a) At wh...

Q: Old Faithful geyser in Yellowstone Park erupts at approximately 1-hour

Old Faithful geyser in Yellowstone Park erupts at approximately 1-hour intervals, and the height of the fountain reaches 40.0 m (Fig. P9.47). (a) Consider the rising stream as a series of separate dro...

Q: The Venturi tube shown in Figure P9.48 may be used

The Venturi tube shown in Figure P9.48 may be used as a fluid flowmeter. Suppose the device is used at a service station to measure the flow rate of gasoline (p = 7.00 x 102 kg/m3) through a hose havi...

Q: A square metal sheet 3.0 cm on a side and

A square metal sheet 3.0 cm on a side and of negligible thickness is attached to a balance and inserted into a container of fluid. The contact angle is found to be zero, as shown in Figure P9.49a, and...
