The pressure in Denver, Colorado (elevation 5280 ft), averages about 24.9 in Hg. Convert this pressure to each indicated unit. c. psi

검증된 단계별 안내

Start by understanding the units involved: 1 inch of mercury (in Hg) is a unit of pressure, and psi stands for pounds per square inch.

Use the conversion factor between inches of mercury and psi. The conversion factor is: 1 in Hg = 0.491154 psi.

Multiply the given pressure in inches of mercury by the conversion factor to convert it to psi. That is, multiply 24.9 in Hg by 0.491154 psi/in Hg.

Set up the multiplication: 24.9 in Hg * 0.491154 psi/in Hg.

Perform the multiplication to find the pressure in psi.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Pressure Units

Pressure is a measure of force applied per unit area and can be expressed in various units, including inches of mercury (in Hg), pounds per square inch (psi), and pascals (Pa). Understanding how to convert between these units is essential for solving problems related to pressure in different contexts.

Conversion Factors

Conversion factors are numerical values used to convert a quantity from one unit to another. For pressure, specific conversion factors exist, such as 1 in Hg being approximately equal to 0.491 psi. Mastery of these factors allows for accurate and efficient unit conversions in calculations.

Atmospheric Pressure

Atmospheric pressure is the pressure exerted by the weight of the atmosphere above a given point. It varies with altitude; for example, at higher elevations like Denver, the atmospheric pressure is lower than at sea level. Recognizing how elevation affects pressure is crucial for understanding real-world applications and conversions.
