You are trying to find a way to bring electricity to a
remote village in order to run a water-purifying
device. A donor is willing to provide battery chargers
that connect to bicycles. Assuming the water-purifi-
cation device requires 18.6 kWoh daily, how many
bicycles would a village need if a person can average
100 W while riding a bicycle? Is this a useful way to
help the village? Evaluate your findings for strengths
and weaknesses. Summarize your comments and
suggestions in a letter to the donor.

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 ˚f and standard atmospheric pressure, what is the value of the mach number?
