Given the atmospheric pressure is 10 5pa what is a gauge pressure of 0.55 mpa equal to?
To determine the gauge pressure, we need to subtract the atmospheric pressure from the given pressure.
Given:
Atmospheric pressure = 10^5 Pa
Gauge pressure = 0.55 MPa = 0.55 * 10^6 Pa
To find the gauge pressure, we subtract the atmospheric pressure from the given pressure:
Gauge pressure = Given pressure - Atmospheric pressure
= (0.55 * 10^6) Pa - (10^5) Pa
= 0.55 * 10^6 - 10^5 Pa
= 0.55 * 10^6 - 1 * 10^5 Pa
= 0.55 * 10^6 - 0.1 * 10^6 Pa
= (0.55 - 0.1) * 10^6 Pa
= 0.45 * 10^6 Pa
= 4.5 * 10^5 Pa
Therefore, the gauge pressure of 0.55 MPa is equal to 4.5 * 10^5 Pa.
