Water at a gauge pressure of 3.8 atm at street level flows into an office building at a speed of 0.65 m/s through a pipe 5.6 cm in diameter. the pipe tapers down to 2.6 cm in diameter by the top floor, 20 m above (fig. 10-53), where the faucet has been left open. calculate the flow velocity and the gauge pressure in such a pipe on the top floor. assume no branch pipes and ignore viscosity.

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?
