Question

Please show the detail work

1. How long will an E cylinder last if the flow rate is set at 2, and there is 2000 PSIG on the pressure gauge?

2. What is the total flow for a 24% venture mask set at 5 liters per minute at the flow meter?

3. How long will an H cylinder last if the flow rate is set at 15, and there is 2000 PSIG on the pressure gauge?

4. What is the total flow for a 30% venture mask set at 20 liters per minute at the flow meter?

5. How long will an H cylinder last if the flow rate is set at 10, and there is 1000 PSIG on the pressure gauge?

6. What is the total flow for a 40% venture mask set at 10 liters per minute at the flow meter?

Answer 1

(a)Above mentioned table shows

(a)How long will an E cylinder last if the flow rate is set at 2, and there is 2000 PSIG on the pressure gauge it lasts for 5 hours.

(b)Venturi mask

Delivers 24-60% oxygen,differentcolours deliver different rates.

Flow rate: Varies with colour. The correct flow rate to use with each colour it is shown on mask, along with the percentage of oxygen delivered.

BLUE = 2-4L/min = 24% O2.

(c)H-cylinders hold approximately 7107 liters of medical grade oxygen and are far too heavy to be considered portable. At a use rate of 1 LPM, these volumes equate to approximately 11 hours.

(d)BLUE = 2-4L/min = 24% O2

WHITE = 4-6L/min = 28% O2

YELLOW = 8-10L/min = 35% O2

RED = 10-12L/min = 40% O2

GREEN = 12-15L/min = 60% O2

(e) approx. 9hrs

(f)total flow for a 40% venture mask set at 10 liters per minute at the flow meter is

RED = 10-12L/min = 40% O2
