Answer :
To determine the absolute pressure when the gauge pressure is given, we need to consider both the gauge pressure and the atmospheric pressure. Here is the step-by-step process:
1. Understand the Concept:
- Gauge Pressure: This is the pressure measured by a gauge, and it does not account for atmospheric pressure.
- Absolute Pressure: This is the total pressure exerted, including atmospheric pressure. It can be calculated using the formula:
[tex]\[
\text{Absolute Pressure} = \text{Gauge Pressure} + \text{Atmospheric Pressure}
\][/tex]
2. Given Values:
- Gauge Pressure = 114 kPa
- Atmospheric Pressure is typically about 100 kPa (it can vary slightly but is often close to 101.3 kPa).
3. Calculation:
- Using the formula above, we combine the gauge pressure and the atmospheric pressure:
[tex]\[
\text{Absolute Pressure} = 114 \text{ kPa} + 100 \text{ kPa} = 214 \text{ kPa}
\][/tex]
So, the absolute pressure when the gauge pressure is 114 kPa is 214 kPa.
