Where is the air pressure highest and lowest?
The air pressure is highest in areas which are the coolestÊwhich leads to air sinkingÊand creating high pressure at the surface. The opposite is true for areas which are warmest. This causes the air to rise, making pressure at the surface lower.
The lowest level of the deepest mine (In South Africa), will have the highest atmospheric pressure. But because of the forced ventilation and cooling systems needed, the air pressure at the lowest levels of the mine will not represent natural atmospheric pressures. [unless the ventilation systems fail!}
What position is blood pressure normally the highest and lowest? If a person was sitting, reclining, or standing, which position would cause the blood pressure to be highest and lowest? Also, if there was an increase in blood viscosity, cardiac ouput, and diameter of the arterioles would this constitute to an increase in blood pressure as well? blood pressure (BP) is usuall lowest standing position and highest in supine (reclining) position. This is because the…
Pressure gradient is the rate of pressure change as you change position, not just the difference between the lowest pressure and the highest pressure, but how great (or small) the physical distance between them. Since it the pressure difference that make air flow (wind) the greater the pressure gradient, the greater the wind.
