Question

How would you do this? For EMT

Answer 1

Answer:

83.2

Explanation:

Tank constant = 1.56

Safe Residual Pressure = 200

Flow = 15

Pressure = 1000 PSI

Duration = ?

1.56 * (1000-200) = 1248

1248/ 15 = 83.2

Formula: (Tank constant * (Tank pressure - Safe Residual Pressure)) / Flow Rate
