Answer:
the absolute pressure in the chamber is 57 kPa
Explanation:
given information:
vacuum's pressure, P₁ = 35 kPa
atmospheric pressure, P₀ = 92 kPa
to find the absolute pressure in he chamber, we can use the following equation:
[tex]P_{abs} =P_{atm} - P_{v}[/tex]
where
[tex]P_{abs}[/tex] = absolute pressure
[tex]P_{atm}[/tex]= atmospheric pressure
[tex]P_{v}[/tex]= vacuum pressure
so,
[tex]P_{abs} =P_{atm} - P_{v}[/tex]
= 92 kPa - 35 kPa
= 57 kPa
Answer:
57 kPa.
Explanation:
Absolute pressure is zero-referenced against a perfect vacuum, so it is equal atmospheric pressure to vacuum gauge pressure.
Mathematically,
Pab = Patm - Pvac
Given:
Pvac = 35 kPa
Patm = 92 kPa
Pab = 92 - 35
= 57 kPa.
