A man attaches a divider to an outdoor faucet so that water flows through a single pipe of radius 9.25 mm into four pipes, each with a radius of 5.60 mm. If water flows through the single pipe at 1.45 m/s, calculate the speed (in m/s) of the water in the narrower pipes.

Hot water with a density of 980 kg/m3 flows through a 51.2 mm diameter round pipe at 1.25 m/s.  What is the mass flow rate (in kg/s) of the water  How many significant figures should be used in the final answer?

If a kitchen sink has a volume of 20 L. Water flows in the sink with a mass flow rate of 0.5 kg/s. If the drain is closed, how long, in seconds, does it take for the sink to fill up?  Density of water = 1000 kg/m3

A water barometer is used to measure air pressure in a duct where the air is being forced to ventilate a building. One end of the barometer is open to the atmosphere, and the other end is open to the inside of the ductwork.  When the tube is bent in the shape of a U, the technician notes that the water level on the side toward the duct is lower than the side toward the atmosphere by 13.4 cm.  What is the pressure difference in N/m2?  The density of water is 1 gm/cm3  or 1000 kg/m3.   Use 9.8 m/s2 for the acceleration of gravity.

Water flows in the system shown below. The flow exits the pipe at a speed of 4.0 m/s.(a). What is the water pressure when it exits the pipe?(b). What is the height of the column of water?

A horizontally oriented hypodermic syringe has a barrel diameter of 1.2 cm and a needle diameter of 2.4 mm. A plunger pushes liquid in the barrel at a rate of 4.0 mm/s. Calculate the flow rate of liquid in both parts of the syringe (in mL/s) and the velocity of the liquid emerging from the needle.

(a) If it takes 1.85 min to fill a 24.0 L bucket with water flowing from a garden hose of diameter 3.50 cm, determine the speed at which water is traveling through the hose. Answer ___________ m/s (Enter a Number) (b) If a nozzle with a diameter three-fifths the diameter of the hose is attached to the hose, determine the speed of the water leaving the nozzle. Answer ___________ m/s (Enter a Number)
