Pressure Conversion Problems Worksheet
Pressure is a physical quantity that measures the force applied perpendicular to the surface of an object per unit area. There are several units of pressure, and it is often necessary to convert between them to solve problems. This worksheet provides formulas, sample problems, and a step-by-step guide to help you convert pressure units.
Unit Conversion Formulas
The following formulas can be used to convert pressure from one unit to another:
- To convert pressure from pascals (Pa) to atmospheres (atm):
P (atm) = P (Pa) / 101325
- To convert pressure from kilopascals (kPa) to pounds per square inch (psi):
P (psi) = P (kPa) / 6.895
- To convert pressure from torr (mmHg) to bars:
P (bars) = P (torr) / 760
Sample Pressure Conversion Problems: Pressure Conversion Problems Worksheet Answers
The following table shows examples of pressure conversion problems:
| Initial Pressure | Initial Unit | Converted Pressure | Converted Unit | Solution |
|---|---|---|---|---|
| 100000 | Pa | 0.987 | atm | P (atm) = 100000 Pa / 101325 = 0.987 atm |
| 25 | kPa | 3.62 | psi | P (psi) = 25 kPa / 6.895 = 3.62 psi |
| 720 | torr | 0.947 | bars | P (bars) = 720 torr / 760 = 0.947 bars |
Detailed Explanations of Conversion Methods
To convert pressure from one unit to another, you can use the following steps:
- Identify the initial pressure and the unit it is expressed in.
- Choose the appropriate conversion formula based on the initial and desired units.
- Substitute the initial pressure into the conversion formula.
- Calculate the converted pressure.
For example, to convert 25 kPa to psi, you would use the following steps:
- Initial pressure: 25 kPa
- Initial unit: kPa
- Conversion formula: P (psi) = P (kPa) / 6.895
- Converted pressure: P (psi) = 25 kPa / 6.895 = 3.62 psi
Common Errors Made When Converting Pressure Units
There are a few common errors that people make when converting pressure units:
- Using the wrong conversion formula.
- Forgetting to convert the initial pressure to the correct unit before substituting it into the conversion formula.
- Rounding the converted pressure to the wrong number of significant figures.
By following the steps Artikeld in this worksheet, you can avoid these errors and accurately convert pressure units.
