The power (in watts) used to move air out of the lungs is equal to the air pressure (in N/m2) multiplied by the air flow rate (in m3/s). For quiet breathing (where p = 100 N/m2 and flow rate = 100 cm3/s or 1.0 x 10-4 m3/s), the power involved = _____W ; for loud singing (where p = 4000 N/m2 and flow rate = 400 cm3/s or 4.0 x 104 m3/s), the power involved = _____W.
