A small-scale Compressed Air Energy Storage (CAES) system uses a rigid tank, whichhas been sized to 1m3. The air storage helps support various fluid power (pneumatics)requirements, but also serves for energy storage (when fully charged).The tank sits in a plant room having a temperature of 25oC at 1 atmosphere (101.325kPa).When delivered new and installed the tank (and the ambient air it contains) is assumedinitially at the same steady state conditions in the plant room. The tank can be filled with(dry) air to a maximum pressure of 300bar. When left in the plant room, the pressurised airtank eventually attains the plant room temperature.You may assume:> Steady state conditions apply> Negligible changes in kinetic and potential energy> Thermal mass of the tank (metal) is negligible Apply the ideal gas equation and calculate the mass of 25oC air (units: kg) in the fullypressurised tank.
