## Barlow's formula for pipe Solution

STEP 0: Pre-Calculation Summary
Formula Used
pressure = ((2)*(Applied stress)*(Wall thickness))/(Outside diameter)
P = ((2)*(σ)*(t))/(Do)
This formula uses 3 Variables
Variables Used
Applied stress - Applied stress is denoted by the symbol σ. (Measured in Pascal)
Wall thickness - Wall thickness is simply the width of the wall that we are taking under consideration. (Measured in Meter)
Outside diameter - Outside diameter is the diameter of the outside surface. (Measured in Millimeter)
STEP 1: Convert Input(s) to Base Unit
Applied stress: 100 Pascal --> 100 Pascal No Conversion Required
Wall thickness: 5 Meter --> 5 Meter No Conversion Required
Outside diameter: 10 Millimeter --> 0.01 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
P = ((2)*(σ)*(t))/(Do) --> ((2)*(100)*(5))/(0.01)
Evaluating ... ...
P = 100000
STEP 3: Convert Result to Output's Unit
100000 Pascal --> No Conversion Required
100000 Pascal <-- Pressure
