However, the dynamics of airflow, from morphologic considerations alone, may conceivably be different in the monkey than in the horse.

However, when wing-cars requiring air-flow venturis came along in the late 1970s, the wide, flat layout obstructed the airflow and became obsolete.

However the filter itself can increase noise if it restricts airflow too much, or is not cleaned, requiring a larger or faster fan to handle the pressure drop behind the filter.

However, that also means they have greatly reduced ability to alter the airflow to maneuver the aircraft.

( However, pitot pressure can suffer alignment error if the pitot tube is not aligned directly into the oncoming airflow.

However, they do not regulate engine speed very accurately and are affected by air density, as well as external conditions that may influence airflow.

However, additional airflow for ventilation usually requires intake and exhaust blowers.

However, when engine speed increases, the second runner is opened, decreasing airflow speed, but increasing the airflow volume, better matching the engine's airflow needs at higher revolutions.

However, the release of the Pentium II in 1997 highlighted the flaws of the format, as a good airflow was important in Pentium II systems, owing to the relatively high heat dispersal requirements of the processor.

However, with a turbojet or turbofan, the problem arises when the engine is throttled back, causing a mismatch between intake airflow and engine mass flow.

However, the total airflow is lower for the amount of energy consumed than for a more conventional fan.

However, other types of airflow may require the spoiler to operate differently and take on vastly different physical characteristics.

However, the liquid oil makes cleaning and servicing such air cleaners messy and inconvenient, they must be relatively large to avoid excessive restriction at high airflow rates, and they tend to increase exhaust emissions of unburned hydrocarbons due to oil aspiration when used on spark-ignition engines.
