Question

What is the pressure on the gas when about 200 gallons per minute are escaping, given the formula e = 160/P?

a) 1.3 lb/in.²
b) 19.0 lb/in.²
c) 1.6 lb/in.²
d) 0.8 lb/in.²

Answer 1

Using the provided formula, e = 160/P, and the escape rate of 200 gpm, the pressure on the gas is calculated to be 0.8 lb/in².

To calculate the pressure on the gas when about 200 gallons per minute (gpm) are escaping, we use the given formula e = 160/P, where e is the escape rate in gpm and P is the pressure in lb/in². First, we need to solve the formula for P:

• 
  P = 160/e
  

Since e is given as 200 gpm, we substitute this value into the formula to find P:

• 
  P = 160/200
• 
  P = 0.8 lb/in²
  

Therefore, the pressure on the gas is 0.8 lb/in².
