Actual Circumferential Bolt Spacing [Bs]: = C * sin( pi / n ) ) = 920.000 * sin( 3.142 / 32 ) = 90.176 mm

ASME Moment Multiplier for Bolt Spacing per App. 2 eq. (7) [Bsc]: = max( sqrt( Bs/( 2a + t )), 1 ) = max( sqrt( 90.176 /( 2 * 24.000 + 39.000 )), 1 ) = 1.0181

Distance to Hub Large End[R]: = (C - Bcor) / 2 - g1cor = (920.000 - 806.000 ) / 2 - 17.000 = 40.0000 mm

Distance to Gasket Load Reaction[hg]: = (C - G ) / 2.0 = ( 920.0001 - 856.2029 ) / 2.0 = 31.8986 mm

Distance to Face Pressure Reaction[ht]: = ( R + g1cor + hg ) / 2.0 = ( 40.0000 + 17.0000 + 31.8986 ) / 2.0 = 44.4493 mm
