A tank of N2 has a volume of 100 ft3 and an initial temperature of 80OF. One pound of N2 is removed from the tank, and the pressure drops to 100 psig while the temperature of the gas in the tank drops to 60OF. Assuming N2 acts as an ideal gas, calculate the initial pressure reading on the pressure gauge (psi).
