Absolute pressure is the actual existing pressure, independent of the environment, while gauge pressure is the pressure relative to the exterior environment, which is usually the atmosphere (with a pressure of 1 atm).Convert an absolute pressure of 7.05 × 105 N/m2 to gauge pressure, in pounds per square inch.

Answer:

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 .
