High blood pressure (hypertension) is a common condition in which the long-term force of the blood against your artery walls is high enough that it may eventually cause health problems, such as heart disease. Blood pressure is determined both by the amount of blood your heart pumps and the amount of resistance to blood flow in your arteries.

Air Density Calculator - What is the Density of Air?

For dry air, its density at sea level at 59 °F (15 °C) and 14.7 psi (1013.25 hPa) (mean sea-level pressure), is approximately 0.0765 lb/cu ft (1.225 kg/m³). If you change the air temperature, humidity, or the altitude (and hence the pressure), the air density will change, too.

High and Low Pressure - Your Weather Experts

The slightly inward moving air in low pressure causes air to converge and since it can't move downward due to the surface, the air is forced upward, leading to condensation and precipitation as discussed earlier. The opposite occurs with high pressure. Air is moving away from the high pressure center at the surface (or "diverging") so as ...

High-pressure transformations in CaSiO3 | SpringerLink

Wollastonite transforms to a triclinic high-pressure polymorph, wollastonite II, at pressures > 25 kb. The equilibrium boundary [P(bars)=-4.7×T°C+32.810] has a rather flat negative P-T slope. The rapid reactivity of the transition over at least a 1000° C range, its insensitivity to T and its location around 30 kb are indicative of its potential for a pressure calibration curve at high T.

A high pressure system has higher pressure at its center than the areas around it. Winds blow away from high pressure. Swirling in the opposite direction from a low pressure system, the winds of a high pressure system rotate clockwise north of the equator and counterclockwise south of the equator. This is called anticyclonic flow.
