Standard litre per minute

Okay kiddo, so you know how we use liters to measure how much liquid we have in a bottle or a glass? Well, sometimes we need to measure how much gas is going through a tube or pipe, like when we use oxygen masks in hospitals or when machines need a certain amount of air to work properly.

That's where "standard liters per minute" come in. It's a way of measuring how much gas is flowing through a tube or pipe in a certain amount of time. The "standard" part means we use a specific set of conditions to make sure everyone is measuring the same way.

So let's say we have a pipe that we want to measure how much gas is flowing through. We set up some equipment to measure the gas flow and we make sure the gas is at a certain temperature, pressure, and humidity. This way, everyone who measures the flow is doing it under the same conditions.

Now, we use liters again, but we add "per minute." This means we're measuring how much gas is flowing through the pipe every minute.

So when we say "standard liters per minute," we're talking about a specific way of measuring how much gas is flowing through a pipe every minute, using the same conditions for everyone who measures it.
