Question

Make the indicated pressure conversions. a. 17.3 psi to kilopascals b. 1.15 atm to psi

Short answer

a. 17.3 psi is approximately equal to 119.20 kPa. b. 1.15 atm is approximately equal to 16.90 psi.

Step-by-step solution

a. Convert 17.3 psi to kilopascals (kPa)

To convert 17.3 psi to kPa, we need to multiply it by the conversion factor (1 psi = 6.89476 kPa). \( 17.3 \, \text{psi} \cdot 6.89476 \, \frac{\text{kPa}}{\text{psi}} \) Now, perform the multiplication: \(17.3 \cdot 6.89476 = 119.201708\) kPa So, 17.3 psi is approximately equal to 119.20 kPa.

b. Convert 1.15 atm to psi (pound per square inch)

To convert 1.15 atm to psi, we need to multiply it by the conversion factor (1 atm = 14.6959 psi). \( 1.15 \, \text{atm} \cdot 14.6959 \, \frac{\text{psi}}{\text{atm}} \) Now, perform the multiplication: \(1.15 \cdot 14.6959 = 16.900085\) psi So, 1.15 atm is approximately equal to 16.90 psi.

Key concepts

Understanding Psi to Kilopascals Conversion

Pressure conversion is a vital concept in various scientific and engineering fields. PSI, or pounds per square inch, and kilopascals (kPa) are units used to measure pressure. The conversion from psi to kilopascals is straightforward once we know the conversion factor.
To convert psi to kPa, remember this key conversion factor:

• 1 psi = 6.89476 kPa

So, if you want to convert 17.3 psi to kPa, multiply the psi value by this conversion factor:

• 17.3 psi × 6.89476 = 119.20 kPa

This calculation tells us that 17.3 psi is approximately 119.20 kPa, allowing us to interchange these units easily in calculations. This conversion is particularly useful when dealing with different pressure systems and instruments that may use either of these units.

The Process of Converting Atmospheres to Psi

Atmospheres (atm) and psi (pounds per square inch) are both units commonly used to express pressure. While atmospheres are typically used in more scientific settings, psi is familiar to many, especially in fields involving mechanics and pneumatic systems.
To convert from atmospheres to psi, utilize this conversion factor:

• 1 atm = 14.6959 psi

For example, let's say you have 1.15 atm and wish to convert it to psi. Multiply the number of atmospheres by the conversion factor:

• 1.15 atm × 14.6959 = 16.90 psi

Thus, 1.15 atm converts to approximately 16.90 psi. This conversion is helpful when transitioning between different pressure systems or when comparing pressures in contexts where this unit is more appropriate.

Introduction to Pressure Units Conversion

Pressure is an important physical quantity that can be expressed in various units across different contexts. Common units include psi, kPa, and atm. Each has its applications and relevance in specific scientific, engineering, or daily settings.
Understanding how to interconvert between these units allows for flexibility in problem-solving and communication of data:

• PSI to kPa: Use the conversion factor 1 psi = 6.89476 kPa.
• Atm to Psi: Use the conversion factor 1 atm = 14.6959 psi.

Mastering these conversions ensures accurate representation of pressure values, which is crucial for applications such as calibration of equipment, scientific experiments, or any scenario where pressure plays a role. With these conversion techniques, any problem involving different pressure units becomes manageable and straightforward.
