Assume it takes 7.00 min to fill a 30.0-gal gasoline tank, (a) (Calculate the rate at which the tank is filled in gallons per second. (b) (Calculate the rate at which the tank is filled in cubic meters per second. (c) Determine the time interval, in hours, required to fill a 1.00-m3 volume at the same rate. (1 U.S. gal = 231 in.3)

The inside volume of a house is equivalent to that of a rectangular solid 13.0 m wide by 200 m long by 2.75 m high. The house is heated by a forced air gas heater. The main uptake air duct of heater is 0.300 m in diameter. What is the average speed of the duct if it carries a volume equal to that of the house’s interior every 15 minutes?

A solid rubber ball has a radius of 18 centimeters. What is its volume in m3? V = m3 %D Hard rubber has a density of 1200 kg/m'. What is the mass of this ball? unit = W

Suppose you want to fill up a swimming pool that has a capacity of 80500 L. a. Calculate how many hours it would take to fill this pool using a garden hose delivering 59 L/min.  b. How many seconds would it take to fill this pool if you could divert a moderate size river, flowing at 5000 m^3/s, into it?

An aquatic organism needs to be neutrally buoyant to stay at a constant depth. Fish accomplish this with an internal swim bladder they can fill with air that they take in from the water through their gills. One complication is that the pressure in the swim bladder matches that of the surrounding water, but the water pressure changes with depth. Because the volume of a gas is inversely proportional to pressure (as you may already know if you have studied the ideal-gas law), the volume of air in a fish's swim bladder decreases with depth unless the fish actively adds more air.

An auditorium measures 40.0 m x 20.0 m x 12.0 m. The density of air is 1.20 kg/m3. What are (a) the volume of the room in cubic feet and (b) the weight of air in the room in pounds?
