This formula uses 1 Constants, 5 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Actual Bolt Area - (Measured in Square Meter) - Actual Bolt Area is defined as cross-sectional area of the bolts using root diameter of thread or least diameter of an unthreaded portion (if less), to prevent damage to the gasket during bolting-up.
Gasket Unit Seating Load - (Measured in Pascal) - Gasket Unit Seating Load is the seating load on per unit area o the sealing gasket.
Gasket Diameter - (Measured in Meter) - Gasket Diameter is a straight line passing from side to side through the centre of a gasket.
Gasket Width - (Measured in Meter) - Gasket Width is defined as the thickness of the gasket measured along the radial direction of the gasket.
Stress Required for Gasket Seating - (Measured in Pascal) - The Stress Required for Gasket Seating is defined as the value of the stress in the gasket required for the seating or the installment of the gasket.

STEP 1: Convert Input(s) to Base Unit

Gasket Unit Seating Load: 3.85 Newton per Square Millimeter --> 3850000 Pascal (Check conversion here)
Gasket Diameter: 32 Millimeter --> 0.032 Meter (Check conversion here)
Gasket Width: 4.1 Millimeter --> 0.0041 Meter (Check conversion here)
Stress Required for Gasket Seating: 25.06 Newton per Square Millimeter --> 25060000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

A_b = (2*pi*y_sl*G*N)/(σ_gs) --> (2*pi*3850000*0.032*0.0041)/(25060000)

Evaluating ... ...

A_b = 0.000126646550772648

STEP 3: Convert Result to Output's Unit

0.000126646550772648 Square Meter -->126.646550772648 Square Millimeter (Check conversion here)

FINAL ANSWER

126.646550772648 ≈ 126.6466 Square Millimeter <-- Actual Bolt Area
