Flange pressure developed due to tightening of bolt Solution

STEP 0: Pre-Calculation Summary
Formula Used
Flange pressure = Number of Bolts*Bolt Load in Gasket Joint/(Area*Torque Friction Coefficient)
pf = n*Fb/(A*Cu)
This formula uses 5 Variables
Variables Used
Flange pressure - (Measured in Pascal) - Flange pressure refers to the pressure exerted onto the flange (a projecting flat rim, collar, or rib on an object, serving for strengthening or attachment).
Number of Bolts - Number of Bolts is simply defined as the number of bolts that are under our consideration.
Bolt Load in Gasket Joint - (Measured in Newton) - Bolt Load in Gasket Joint is defined as the load that is applied by the bolts onto the gasketed joint.
Area - (Measured in Square Meter) - The area is the amount of two-dimensional space taken up by an object.
Torque Friction Coefficient - Torque Friction Coefficient are values based on friction coefficients of 0.12 between threads and 0.14 between nut and washer or head and washer, as manufactured.
STEP 1: Convert Input(s) to Base Unit
Number of Bolts: 4 --> No Conversion Required
Bolt Load in Gasket Joint: 18150 Newton --> 18150 Newton No Conversion Required
Area: 50 Square Meter --> 50 Square Meter No Conversion Required
Torque Friction Coefficient: 0.14 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
pf = n*Fb/(A*Cu) --> 4*18150/(50*0.14)
Evaluating ... ...
pf = 10371.4285714286
STEP 3: Convert Result to Output's Unit
10371.4285714286 Pascal -->0.0103714285714286 Megapascal (Check conversion here)
FINAL ANSWER
0.0103714285714286 Megapascal <-- Flange pressure
(Calculation completed in 00.016 seconds)
