question

How many full strokes of a bicycle pump (chamber 4.0 cm diameter and 40.0 cm long) would you need to make in order to pump up an automobile tire from a gauge pressure of zero to 24 pounds per square inch (psi)? Assume tem-perature stays constant at 25°C and atmospheric pressure is one atmosphere. Note, that gauge pressure measures only the excess over atmospheric pressure. A typical tire volume is about 25 liters.
