Short Answer

Question: Convert an absolute pressure of to gauge pressure in (This value was stated to be just less than in Example 13.9. Is it?)

Answer

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

See the step by step solution

Step by Step Solution

Step 1: Introduction

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

Step 2: Given parameters and conversion units

Absolute pressure = 7×105N/m2

gauge pressure =5.99×105N/m2

1 N = 0.2251b

1 meter = 39.37 inches

Step 3: Calculate the pressure in new units

5.99×105N/m2=5.99×105×0.22539.37×39.37lb/in2=86.95lb/in2

Therefore, the pressure in new units is which was stated as just less than 90 1b/in2
