The ratio of initial and final pressures in a tank, denoted as “pi/pf,” represents the relationship between the initial pressure (pi) and the final pressure (pf) within a closed container or system. pi: Initial Pressure – This is the pressure at the beginning of a process, such as the pressure inside a tank or a closed system before any changes occur. It is typically measured in units like Pascals (Pa), atmospheres (atm), or other pressure units. pf: Final Pressure – This is the pressure at the end of a process or after any changes have taken place. It could be higher or lower than the initial pressure, depending on the specific scenario and the type of process involved.Â
