2. The force which is created by the amount of liquid or gas in a container: The pressure in the sealed pot made it possible for the food to be prepared in a shorter amount of time than without such a special pot.
3. The act of persuading or threatening a person to do something: Jack put a lot of pressure on his sister so that she would not reveal his secret to his girlfriend.
4. The stress and demands a person experiences when very important issues are pending and must be done in a short time: Sometimes Mrs. Smart experienced a lot of pressure when she had to finish correcting the exams to return to the students the following day!
With an increasing altitude, the atmospheric pressure decreases. For example, at 30,000 feet, approximately the height of Mt. Everest, the air pressure is 4.3 pounds per square inch.
The atmospheric pressure at any point in an atmosphere is due solely to the weight of the atmospheric gases above the point concerned.
Although pneumatic and mechanical transducers are commonly used, electrical measurement of pressure is often preferred because of a need for long-distance transmission, higher accuracy requirements, more favorable economics, or quicker responses.
Electrical pressure transducers may be classified depending on the operating principle as resistive transducers, strain gages, magnetic transducers, crystal transducers, capacitive transducers, or resonant transducers.
2. The pressure exerted by mist, or clouds, in the atmosphere which are independent of any other gases or water particles.
2. The force exerted by something pressing or squeezing an area.
The tires on a car are under pressure because air, forced into them, pushes against their rubber walls.
The atmospheric pressure decreases as the higher altitude increases.
