Convert an absolute pressure of 7 x 105 N/M2 to gauge pressure in lb/in2 (This value was stated to be just less than 90.0 lb/in2 in Example 13.9. Is it?)

Short Answer

Expert verified

Pressure in terms of lb/in2 is 86.95 lb/in2.

Step by step solution

01

Introduction

We use conversion units to convert N to lb and meters to inches.

02

Given parameters and conversion units

Absolute pressure = 7 x 105N/M2

gauge pressure = 5.99 x 105N/m2

1 N = 0.225 lb

1 meter = 39.37 inches

03

Calculate the pressure in new units

5.99ร—105N/m2=5.99ร—105ร—0.22539.37ร—39.37lb/in2=86.95lb/in2

Therefore, the pressure in new units is 86.95 lb/in2which was stated as just less than 90 lb/in2.
