Water is flowing through a hose. It comes out of the tap at a pressure of, velocity of
, and height of
. It leaves the nozzle at a pressure of
and a height of
. What is the velocity of the water when it leaves the hose?
At a dock, a metal plate is completely submerged and attached to an underwater wall. The side of the metal plate is exposed to the ocean, and to the flow of water caused by tides. The plate has dimensions of and
. If the current has a speed of
at maximum tidal flow, how much force will the water exert on the metal plate?
Suppose that a huge tank 50m high and filled with water is open to the atmosphere and is hit with a bullet that pierces one side of the tank, allowing water to flow out. The hole is 2m above the ground. If the hole is very small in comparison with the size of the tank, how quickly will the water flow out of the tank?
A venturi is a T-shaped tube in which the vertical tube is in water. A high-speed stream of air is forced through the horizontal tube. As a result, water rises in the vertical tube, as shown in the given figure. If air is forced through the horizontal tube at , how high will the water rise in the vertical tube?
As the velocity of a fluid increases, what happens to the pressure? Assume both states of the fluid are at the same height and the pipe has a constant diameter.
Water is flowing through a hose. It comes out of the tap at a pressure of, velocity of

. What is the pressure of the water when it leaves the hose?
Water is flowing through a horizontal pipe. Water enters the left side of the pipe at a pressure and a velocity of
. It leaves the pipe at a velocity of
. What is the pressure of the water when it leaves the pipe?
.
Suppose that a fluid with a density of flowing through a horizontal pipe at a speed of
has a pressure of 100000Pa. If this fluid then starts flowing through the pipe at a speed of
, what is the new pressure that this fluid exerts?
Suppose a physician is considering the flow of blood through a blood vessel. Dissolved within the blood are several important gasses, such as oxygen. If there is a blood clot that is partially obstructing one of the blood vessels, how will the blood's partial pressure of oxygen change as it is flowing past this clot?
Water is flowing at a rate of through a tube with a diameter of 1m. If the pressure at this point is 80kPa, what is the pressure of the water after the tube narrows to a diameter of 0.5m?
