It sounds like you already know the answer you want, but the answer depends upon which certification agency you want the answer for. For most "sport" agencies, the maximum operating partial pressure is 1.40 with an emergency contingency pressure of 1.60. However ANDI, sets the maximum operation pressure at 1.45 and some technical agencies set it at 1.3 once you go deeper than 100 feet or 30 meters.
You know, the factors of partial pressure
To calculate Kp from partial pressures, you use the formula Kp (P products)(coefficients of products) / (P reactants)(coefficients of reactants), where P represents the partial pressures of the substances involved in the reaction.
total pressure = sum of all partial pressures.
Dalton's law of partial pressures) states that the total pressure exerted by the mixture of non-reactive gases is equal to the sum of the partial pressures of individual gases.
The pressure of each gas in a mixture is called the partial pressure of that gas.
The concept that the total pressure of a mixture of gases is the sum of their partial pressures was developed by John Dalton in the early 19th century. This idea forms the basis of Dalton's Law of Partial Pressures.
The total pressure of a gas mixture is the sum of the individual pressures.
Dalton's Law of partial pressures states that the total pressure of a gas mixture is equal to the sum of the partial pressures of each individual gas in the mixture. This law is based on the idea that each gas in a mixture behaves independently of the others. Mathematically, it can be expressed as P total = P1 + P2 + ... + Pn, where P total is the total pressure and P1, P2, ...Pn are the partial pressures of each gas.
The law of partial pressures is also known as Dalton's law. It states that: Ptotal = Pa + Pb + PC + ... + Pn The partial pressure of each gas will add up to to the total pressure of the gas.
The partial pressure is the pressure exerted by just one gas in the mixture.
The total pressure of a gas mixture is the sum of the individual pressures.
