A large water tank is filled to a depth of 12.7 m. A leak develops in the side of the tank and water shoots out at a speed of 6.8 m/s. At what height h above the bottom is

Water (density = 1000 kg/m3) flows through a fire hose with a velocity of 5.0 m/s and a pressure of 150,000 Pa. At the nozzle, the pressure is 101,300 Pa, and there is no change in height. What is the velocity of the water exiting the nozzle?

A metre long narrow bore held horizontally (and closed at one end) contains a 66 cm long mercury thread, which traps a 18 cm column of air. What happens if the tube is held vertically with the open end at the bottom ?

A tank holds a large amount of water. A pipe is connected to the tank at the upper end and is open to the air at the lower end (see figure).The upper end of the pipe is h1 = 1.90-m above the ground. The lower end of the pipe is h2 = 0.570-m above the ground. The water at the upper end of the pipe has a speed of 0.640 m/s. The water at the lower end of the pipe has a speed of 8.50 m/s.What is the pressure in the water in the pipe at the upper end of the pipe?

A pump is used to empty a 5600 L wading pool. The water exits the 2.0-cm-diameter hose at a speed of 2.2 m/s . How long will it take to empty the pool?

A sump pump (used to drain water from the basement of houses built below the water table) is draining a flooded basement at the rate of 0.700 L/s, with an output pressure of 2.00 x 105 N/m². You may neglect frictional losses in both parts of this problem. (a) The water enters a hose with a 3.00 cm inside diameter and rises 3.00 m above the pump. What is its pressure (in N/m²) at this point? N/m² (b) The hose goes over the foundation wall, losing 1.70 m in height, and widens to 4.00 cm diameter. What is the pressure now (in N/m²)? N/m²

Please answer this. I will surely upvote!!!

In the figure, the fresh water behind a reservoir dam has depth D = 14.0 m. A horizontal pipe 3.51 cm in diameter passes through the dam at depth d= 5.62 m. A plug secures the pipe opening. (a) Find the magnitude of the frictional force between plug and pipe wall. (b) The plug is removed. What water volume exits the pipe in 2.00 h? (a) Number (b) Number Units Units

Suppose you spray your sister with water from a garden hose. The water is supplied to the hose at a rate of 0.497×10−3 m3/s and the diameter of the nozzle you hold is 5.41×10−3 m. At what speed v does the water exit the nozzle?
