Answer:
Step-by-step explanation:
gauge pressure = absolute pressure - atmospheric pressure
= 7.05 x 10⁵ - 1.01 x 10⁵
= 6.04 x 10⁵ N / m²
To convert it into pounds per square inch , we shall apply conversion formula
1 pound per square inch (psi ) = .06895 x 10⁵ N/ m²
6.04 x 10⁵ N / m²
= 6.04 / .06895 psi
= 87.6 psi .
