Question: The pressure exerted by a person s lungs can be measured
The pressure exerted by a person’s lungs can be measured by having the person blow as hard as possible into one side of a manometer. If a person blowing into one side of an open tube manometer produces an 80-cm difference between the heights of the columns of water in the manometer arms, what is the gauge pressure of the lungs?
