Question:medium

An agricultural worker expired 150 litres of air having 16% oxygen in 5 minute duration. What is the oxygen consumption in litre per minute to perform the activity?

Always assume the standard atmospheric oxygen concentration is \(21%\) for inhaled air.
The difference between inhaled and exhaled oxygen concentrations (typically \(5%\)) represents the proportion of oxygen absorbed by the body.
