- $P+P_{a}$
- $\frac{P-P_{a}}{2}$
- $2P-P_{a}$
- $\frac{P+P_{a}}{2}$
- $P-P_{a}$
Show Solution
Verified By Collegedunia
The Correct Option is
Solution and Explanation
Step 1: Concept
Absolute pressure $P$ is the sum of atmospheric pressure $P_a$ and gauge pressure $P_g$.
Step 2: Analysis
$P = P_a + P_g$.
Step 3: Calculation
Gauge pressure $P_g = P - P_a$. Final Answer: (E)
Absolute pressure $P$ is the sum of atmospheric pressure $P_a$ and gauge pressure $P_g$.
Step 2: Analysis
$P = P_a + P_g$.
Step 3: Calculation
Gauge pressure $P_g = P - P_a$. Final Answer: (E)
