Physics and Chemistry -Cylinders

Question 1

gasses liquefy if sufficient pressure is applied and the temperature is below a critical value called what

Answer 1

the critical temperature

Question 2

if the flow of the O2 from an E cylinder is 5 L/m, how long will is take for the cylinder to empty

Answer 2

full E cylinder 2200 psi
2200 x 0.3 = 660L
660L / 5 L/min = 132 min

Question 3

If the pressure in a E cylinder of O2 is 1,100 psi and the flow is 5L/min , how long will it take for the tank to empty

Answer 3

1,100 x 0.3 = 330L

330L / 5/min = 66 min
