The air moved by an attic ventilation fan blows out, sucking in fresh cooler air through the intake vents, commonly around the eaves or overhangs of the attic.
Alternating Current (AC) reverses its flow constantly, unlike DC (constant current) which flows in one direction only.
valves
a pressure greater than the osmotic pressure is applied in the opposite direction osmosis is occurring.
The answer is Water Shed
from the south towards the equator
More insulation in the attic, better air flow through the attic, direction the roof is pointing, less sun, the pitch of the roof, Any or all of these.
The reason baffles are used is so the blow in insulation does not cut off the air flow coming in from the soffit vents. If you are satisfied that your batts provide enough flow at the eves then call it good. This assumes you have ventilation at the ridge, otherwise it will not be very useful.

Ventilation is the mass flow of air into and out of the lungs. Ventilation of the lungs is necessary as it brings oxygen into the body for body processes such as respiration and ventilation of the lungs release carbon dioxide from the body.
in which direction does the river Shannon flow?
Minute ventilation X 3
Ventilation perfusion coupling is the amount of gas reaching alveoli & blood flow in pulmonary capillaries; local autoregulation.
Downward, Downriver, Downhill, the direction gravity pulls everything.
Blood flow doesn't change direction. They always head for the same direction.
So the gas can flow evenly
The direction of lymph flow is always towards the Thoracic Lymph duct .
These are machines dealing with fluids, like (Axial Compressors, pumps and Fans). the term "Axial" is given due to the direction of inward and outward flow. In axial turbo machines the direction of outward flow is the same as the direction of the inward flow since the blades of the machines doesn't change the direction of flow.
