Problem 7: The water of a 14' x 48' metal frame pool can drain from the pool through an opening at the side of the pool. The opening is about h = .06 m below the water level. The capacity of the pool is V = 3770 gallons, the pool can be drained in t = 12.9 mins. Po is the pressure of the atmosphere. o is ne density of the water.

The entrance opening of a horizontal pipe has a radius of 6 cm and water is flowing at .35 m/s. The pressure at opening is 18.5 n/m2 and changes to 23.0 N/m2 at the exit. What is the area of the exit opening?

Please help thank you!

1. A capillary tube of inside diameter d=6mm connects tank A and open container B as shown in Fig.2. The liquid in A,B and capillary CD is water having a specific weight y=9780 N/m³ and a viscosity of μ=0.0008N s/m². The pressure PA-34.5 kPa gage. Neglecting the minor losses at C and D, determine the flow rate Q through the capillary tube. Assume laminar flow from A to B and use h=32μLV/yd² for the friction loss, where V is the water velocity through the capillary tube.

A water intake at a pump storage reservoir (see the figure below) has a cross-sectional area of 0.637 m². The water flows in at a speed of 0.470 m/s. At the generator building, at distance D = 156 m below the intake point, the cross-sectional area is smaller than at the intake and the water flows out at 9.44 m/s. What is the difference in pressure between inlet and outlet? Reservoir Number 202.6 Units D Intake MPa Generator building Outlet-

A container of water has a cross-sectional area of Ac=0.25m2. A piston with mass mp=18kg, sits on top of the water as shown in Figure 1. The height of the water which the piston is sitting on is h1=0.45m. There is a spout located h2=0.17m from the bottom of the tank, open to the atmosphere, and a stream of water exits the spout. The cross-sectional area of the spout is As=8.5 x 10-3m2. A valve on the spout is closed. How much force is the water in the spout exerting on the valve?

A cylinder that is hi = 18.5 cm tall and open on top is filled with water. If a hole is made in the side of the cylinder, Ah Ah = 3.40 cm below the top level, how far x from the base of the cylinder will the stream land? h, Assume that the cylinder is large enough so that the level of the water in the cylinder does not drop significantly. cm
