What is the cylinder constant for an E tank?

The cylinder constant for an E tank is 0.28. This constant is significant for calculating the duration of gas supply from the compressed gas cylinder, particularly oxygen tanks used in emergency medical situations. The formula for estimating how long the tank will last involves multiplying the pressure in the tank by the cylinder constant and then dividing by the flow rate.

In this case, the cylinder constant reflects the specific characteristics of the E tank, such as its volume and the conversion of pressure to usable liters of gas. Understanding this constant is crucial for paramedics, as it helps ensure that they can provide adequate care based on the available supply of oxygen or other gases during emergencies.
