Because a nose peg will prevent any air from accidentally escaping through your nasal passages, assuring an accurate tidal volume and vital capacity result when you blow air out forcefully from your mouth into the spirometer.
because cubic kilometres would be much too big for the accurate volume measure of your average fridge .
a cup is the best unit to measure the capacity of a small drinking glass
Any unit of volume will do the job, but the cup, pint, fluid ounce, or liter will most likely produce the most convenient number.
Measure its dimensions in inches or centimeters, and its volume or capacity in gallons or litres.
there are many unit which measure volume .SI units that measure volume is cubic meter .
the spirometer
No. A spirometer can be used to measure the volume of breath a person can expire but it is impossible to expire your entire lung capacity. This is due to the "dead space" capacity that remains to stop the collapse of the alveoli. As the alveoli are spherical and lined with mucus if they collapse it would be impossble for them to be filled again and so some air must remain within them. It is, however, possible to estimate someone's total lung capacity from the spirometer reading.
Respiratory volume or respiratory minute volume is the volume of air which can be inhaled or exhaled from a person's lung in one minute.It is normally consider when a person on a ventilator for breathing problem due to sickness or injury. It is calculated by taking the tidal volume( or lung volume ) and multiplying it by the respiratory rate( the number of breaths per minute a person is taking).
An anapnograph is a variety of spirometer, a device used to measure the volume of air inspired and expired by the lungs.
