STEP 0: Pre-Calculation Summary
Formula Used
Fb = 11*mti/dn
This formula uses 3 Variables
Variables Used
Initial bolt torque - (Measured in Newton) - Initial bolt torque is defined as initial twisting force acting on bolt.A force that tends to cause rotation.
Nominal Bolt Diameter - (Measured in Meter) - Nominal bolt diameter is the size most commonly associated with screw threads is the nominal diameter.
STEP 1: Convert Input(s) to Base Unit
Initial bolt torque: 2 Newton --> 2 Newton No Conversion Required
Nominal Bolt Diameter: 2.8 Millimeter --> 0.0028 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Fb = 11*mti/dn --> 11*2/0.0028
Evaluating ... ...
Fb = 7857.14285714286
STEP 3: Convert Result to Output's Unit
7857.14285714286 Newton --> No Conversion Required

## < 10+ Bolts and stresses in flange joints Calculators

Bolt Load given Modulus of Elasticity and Increment Length
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
Twisting Moment = (Flange pressure*Area*Torque Friction Coefficient*Diameter of Bolt)/(2*Number of Bolts)
Flange pressure given Twisting moment
Flange pressure = 2*Number of Bolts*Twisting Moment/(Area*Torque Friction Coefficient*Diameter of Bolt)
Flange pressure developed due to tightening of bolt
Flange pressure = Number of Bolts*Bolt Load in Gasket Joint/(Area*Torque Friction Coefficient)
Area = Number of Bolts*Bolt Load in Gasket Joint/(Flange pressure*Torque Friction Coefficient)
Number of Bolts given Flange pressure
Number of Bolts = Flange pressure*Area*Torque Friction Coefficient/Bolt Load in Gasket Joint
Bolt Load in Gasket Joint = Flange pressure*Area*Torque Friction Coefficient/Number of Bolts
Nominal Bolt Diameter given Bolt Load
Initial Bolt Torque given Bolt Load

Fb = 11*mti/dn

Bolt load defined as the load that can be carried at one time a mass or weight supported by bolt.SI unit is kN
