n = pf*a*Cu/Fb
This formula uses 5 Variables
Variables Used
Number of Bolts - Number of Bolts is simply defined as the number of bolts that are under our consideration.
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).
Gasket Area - (Measured in Square Meter) - Gasket Area is the space occupied by a flat surface or the shape of 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.
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.
STEP 1: Convert Input(s) to Base Unit
Flange pressure: 5.5 Megapascal --> 5500000 Pascal (Check conversion here)
Gasket Area: 100 Square Millimeter --> 0.0001 Square Meter (Check conversion here)
Torque Friction Coefficient: 0.14 --> No Conversion Required
Bolt Load in Gasket Joint: 18150 Newton --> 18150 Newton No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
n = pf*a*Cu/Fb --> 5500000*0.0001*0.14/18150
Evaluating ... ...
n = 0.00424242424242424
STEP 3: Convert Result to Output's Unit
0.00424242424242424 --> No Conversion Required
FINAL ANSWER
0.00424242424242424 0.004242 <-- Number of Bolts

Bolt Load given Modulus of Elasticity and Increment Length
Go Bolt Load in Gasket Joint = Modulus of Elasticity*Incremental Length in Direction of Velocity/((Length of joint 1/Area of cross section at the inlet)+(Length of joint 2/Area of cross section at the throat))
Twisting Moment given Flange Pressure
Go Twisting Moment = (Flange pressure*Gasket Area*Torque Friction Coefficient*Diameter of Bolt)/(2*Number of Bolts)
Flange pressure given Twisting moment
Go Flange pressure = 2*Number of Bolts*Twisting Moment/(Gasket Area*Torque Friction Coefficient*Diameter of Bolt)
Flange pressure developed due to tightening of bolt
Go Flange pressure = Number of Bolts*Bolt Load in Gasket Joint/(Gasket Area*Torque Friction Coefficient)
Gasket Area given Flange pressure
Go Gasket Area = Number of Bolts*Bolt Load in Gasket Joint/(Flange pressure*Torque Friction Coefficient)
Number of Bolts given Flange pressure
Go Number of Bolts = Flange pressure*Gasket Area*Torque Friction Coefficient/Bolt Load in Gasket Joint
Bolt Load given Flange pressure
Go Bolt Load in Gasket Joint = Flange pressure*Gasket Area*Torque Friction Coefficient/Number of Bolts
Width of u collar given uncompressed Gasket Thickness
Go Width of u-collar = ((Uncompressed gasket thickness)*(100-Minimum Percentage Compression))/100
Uncompressed gasket thickness
Go Uncompressed gasket thickness = (100*Width of u-collar)/(100-Minimum Percentage Compression)
Minimum percentage compression
Go Minimum Percentage Compression = 100*(1-(Width of u-collar/Uncompressed gasket thickness))
Nominal Bolt Diameter given Bolt Load
Go Nominal Bolt Diameter = 11*Initial bolt torque/Bolt Load in Gasket Joint
Initial Bolt Torque given Bolt Load
Go Initial bolt torque = Nominal Bolt Diameter*Bolt Load in Gasket Joint/11
Bolt load in gasket joint
Go Bolt Load in Gasket Joint = 11*Initial bolt torque/Nominal Bolt Diameter
