We use some equations to calculate the an initial pressure in an air chamber. Three equations that should not lead to redundancy.

Code:

 syms P_air_initi
 V_air_init = ((100000*V_airchamber^1.4)/P_air_initi)^(1/1.4);
 x_airfront_init = V_air_init/A_airchamber;
 eq6 = P_air_initi  -(100000 + rho*g*(H_delivery-(H_airchamber-x_airfront_init))) ==0;
 [sol] = solve(eq6,P_air_initi)
 x_init = x_airfront_init;              % Initial x in the air chamber
 P_init = sol;                              % Initial pressure in air chamber
 V_init = V_air_init;                              % Initial volume air in air chamber
