Part A - Ideal gas law
Engineers are designing a cylindrical air tank and are trying to determine the dimensions of the tank. The
proposed material for the tank is rated to withstand an absolute pressure of 20 MPa at a temperature of 10°C. If
the tank is sized to have a diameter of 200 mm and hold 4.64 kg of air, what must the length of the tank be?
