At O2 Rental, this is one of the most useful queries customers have. Knowing how long a cylinder will last helps you make the right plans, whether you are setting up oxygen assistance for a clinic, hospital, ambulance, or home care arrangement. Two key criteria determine the answer. The cylinder’s size and pressure come first. The regulator’s flow rate, which is often expressed in liters per minute, comes in second.
To meet a range of needs, Oxygen Cylinder Rental in Kolkata medical oxygen cylinders in various capacities. 10 liter, 20 liter, and 47 liter cylinders are common water capacities. The working pressure of these is usually between 150 and 200 bar, depending on the model and the needs of the customer. A 10-liter cylinder holds about 1500 liters of oxygen when filled at 150 pressure. About 7050 liters of oxygen are contained in a 47-liter cylinder at 150 pressure. These figures aid in determining how long the oxygen will persist.
Our Oxygen Cylinder Rental in Dum Dum fundamental formula is straightforward. The duration in minutes is calculated by dividing the total available oxygen in liters by the flow rate in liters per minute. For instance, you have roughly 1500 liters of oxygen if you are using a 10-liter cylinder that is filled to 150 pressure. The cylinder will last around 750 minutes, or 12.5 hours, at a flow rate of 2 liters per minute. The same cylinder will last roughly 300 minutes, or five hours, if the flow rate is raised to five liters per minute. It will last about 150 minutes, or 2.5 hours, at 10 liters each minute.
Let’s now examine a bigger 47-liter cylinder that is filled to 150 bar. With about 7050 liters of oxygen available, it can endure for over 3525 minutes, or nearly 58 hours, at a rate of 2 liters per minute. It will last about 1410 minutes, or about 23 hours, at 5 liters every minute. It will run for roughly 705 minutes, or nearly 11.7 hours, at 10 liters per minute. Although they are approximations, these figures are trustworthy for planning.
