A throttle is the mechanism by which fluid flow is managed by constriction or obstruction.. An engine's power can be increased or decreased by the restriction of inlet gases (by the use of a throttle), but usually decreased.

For the levels to differ the pressure P1 must be greater than P2, hence. P 1 = P 2 + hρg.. If P 1 is the lung pressure, P 0 is the atmospheric pressure, then if the difference is 'h' then lung pressure can calculated as follows.. P 1 = P 0 + hρg.. Example. A man blows into one end of a U-tube containing water until the levels differ by 40.0 cm. if the atmospheric pressure is 1.01 × 105
