For flow in a pipe, the Reynolds number is defined as Re=(VpD)/mu))
Where V is velocity, is density, is viscosity, and D is diameter. Expressed this way, the Reynolds number can be interpreted as

the ratio of viscous to inertial forces.
the ratio of inertial to viscous forces.
the ratio of momentum flux to viscous forces.
the ratio of kinetic energy to viscous forces.

"an open tank has the shape of a right circular cone. the tank is 6 feet across the top and 5 feet high. how much work is done in emptying the tank by pumping the water over the top edge? note: the density of water is 62.4 lbs per cubic foot."

30 points - when can a theory be modified if a new type of technology allows for new observations that raise new questions? a. immediately, while the questions about the theory are being asked b. after new hypotheses related to the theory are tested in experiments c. only after the new observations disprove all parts of the theory d. while scientists begin to think about how the theory could improve

The experiment was repeated many years later but the gases were mixed in a different type of container. a white solid was obtained which was xenon fluoride. predict whether you think 1) krypton and 2) radon will react with fluorine. explain reasons for your predictions
