Pneumatic nail drivers used in construction require 570 cm3 of air at 7 bar and 1 kJ of
energy to drive a single nail. You have been assigned the task of designing a compressed-air
storage tank with enough capacity to drive 500 nails. The pressure in this tank cannot
exceed 35 bar, and the temperature cannot exceed that normally found at a construction
site. What is the maximum pressure to be used in the tank and what is the tank’s volume?
