ducers are used <strong>to</strong> record pressures corre‐<br />

sponding <strong>to</strong> the N segments, and a mass flow<br />

meter is used <strong>to</strong> record air mass flow rate under<br />

the steady state condition. All these recorded<br />

values are then used as the system initial condi‐<br />

tions for the simulation. The transient pressure<br />

different positions along the transmission line<br />
