The inside volume of a house is equivalent to that of a rectangular solid 13.0 m wide by 20.0 m long by 2.75 m high. The house is heated by a forced air gas heater. The main uptake air duct of the heater is 0.300 m in diameter. What is the average speed of air in the duct if it carries a volume equal to that of the house’s interior every 15 minutes?
The flow rate of blood through a m-radius capillary is cm3/s .
What is the speed of the blood flow?
Assuming all the blood in the body passes through capillaries, how many of them must there be to carry a total flow of 90.0 cm3/s?
A container of water has a cross-sectional area of 0.100 m2. A piston sits on top of the water, as shown. There is a spout located 0.150 m 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 m2.
What is the speed of the water as it leaves the spout?
How far from the spout does the water hit the floor? Ignore all friction and dissipative forces.
