In a total-immersion measurement of a woman’s density, she is found to have a mass of 63.5 kg in air and an apparent mass of 0.0875 kg when completely submerged with lungs almost totally empty. a. What mass, in kilograms, of water does she displace?  b. What is her volume, in cubic meters?  c.  Calculate her average density, in kilograms per cubic meter.  d.  If her lung capacity is 1.75 L, is she able to float without treading water with her lungs filled with air? Assume the density of air is 1.29 kg/m3.

A very simple way of measuring the depth of a fluid in a gas station's underground gasoline tank is by using a pressure gauge that measures gauge pressure. Assume the fluid in the tank is gasoline with a density of 700 kg/m3 and g = 9.80 m/s2. If the gauge pressure is 25.9 kPa what is the depth of the gasoline in the tank? Assume 3 significant digits. Watch the units!   A. 3.78 cm   B. 37.8 m   C. 0.378 m   D. 3.78 m   E. 3.78 mm

A round pipe of varying diameter carries petroleum from a wellhead to a refinery. At the wellhead, the pipe's diameter is 53.5 cm and the flow speed of the petroleum is 13.1 m/s. At the refinery, the petroleum flows at 5.25 m/s. What is the volume flow rate of the petroleum along the pipe, and what is the pipe's diameter at the refinery? volume flow rate: m³/s diameter: cm

A plastic ball floats in gasoline. The weight of the ball is 40.0 N, and its volume is 10.0 L (that is 10 × 10-3 m3). Use g = 10.0 m/s2. The density of the gasoline is 680 kg/m3. What is the volume of ball displaced by the gasoline, in Liter?
