Flush Nozzle located in a sphere:

Note: Pmax is determined per PD:5500 Section 3.5.4:

Shell Effective Mean Diameter [D]:

= Di + es + Min(fp/fs, 1 )*tp + cas - caext

= 2351.70 + 9.750 + Min(1536.29 /1536.29 , 1 )*13.000 + 3.000 - 3.000

= 2377.450 mm

Nozzle Mean Diameter [d]:

= do - eb + can - caext

= 219.100 - 11.113 + 3.000 - 0.000 = 210.988 mm

Adjusted value of [Ratio erb/ers]:

= min(fn/fs, 1 ) * erb / ers

= min(1536.294 /1536.294 , 1 ) * 8.113 / 19.750 = 0.4108

Compute the Maximum Pressure [Pmax]

The value of Pmax is 36.122 kgf/cm and is derived as follows:

Required Shell Thickness [esp]

= Pmax * D / ( 4 * fs )

69/88


= 36.122 * 2377.450 / ( 4 * 1536.294 ) = 13.975 mm

Compute Ratio [C.ers/eps]

= C * ers / eps

= 1.0 * 19.750 /13.975 = 1.4133

Compute the Value of [Rho] :

= d/D * sqrt( D / ( 2 * as ))

= 210.988 /2377.450 * sqrt(2377.450 / ( 2 * 19.750 )) = 0.6885

From Graph: Figure 3.5-10 we obtain a value of erb/ers of: 0.4108

Linear Interpolation Points from: Figure 3.5-10

Rho1 Rho Rho2

0.7000 0.6885 0.6000

Cers/eps1 1.4000 0.430 0.360

Cers/eps 1.4133 <- Interpolated 0.4108

Cers/eps2 1.3000 0.530 0.430

As Calculated Nozzle Thickness equals Actual Thickness: Pmax is correct.

Maxium Allowable Radial Force Fzmax and Moment [MBmax]:

Determine the value of [k]:

= min( 2 * fn * eab / ( fs * eac ) * ( eab / d )?, 1 )

= min(2*1536.294 *8.11 /(1536.29 *19.75 ) * (8.11 /210.99 )?, 1)

= 0.471

Determine the value of [LamdaS]:

= d / ( R * eac )?= 210.988 / ( 1188.725 * 19.750 )?

= 1.377

Determine the Maximum Allowable Radial Force: [FZmax]:

= fs *eac? 1.82 + 2.4 ( ( 1 + k )?* LamdaS + 0.91 * k * LamdaS?)

= 1536.3 *19.750?1.82+2.4((1+0.471 )?1.377 +0.91*0.471 *1.377?

= 9700.133 kgf

From Figure 2.1, FZmax must not exceed: 53944.355 kgf

Determine the Maximum Allowable Moment: [MBmax]:

= fs * eac?* d/4 * ( 4.9 + 2 ( ( 1 + k )?* LamdaS + 0.91 * k * LamdaS?)

= 1536.294 * 19.750?* 210.988 /4 *

(4.9 + 2*(1 + 0.471 )?* 1.377 + 0.91 * 0.471 * 1.377 ))

= 2861.787 kgf-m.

From Figure 2.2, Mbmax must not exceed: 13208.207 kgf-m.

Unity Checks per PD:5500 2.4 for Simultaneous Loads:

P/Pmax = 0.097 Fz/Fzmax = 0.101 Mb/Mbmax = 0.224

P/Pmax + Fz/Fzmax + Mb/Mbmax = 0.422

Maximum Allowable Radial Force Fzmax, and Moments Mxmax, Mymax:

Determine the value of [LambdaC]:

= d /( D * eac )?

= 262.897 /(1329.000 * 23.000 )?= 1.504

From Figures 3.1, 3.2 and 3.3:

C2 = 2.040 C3 = 4.914 C4 = 8.087

Maximum Allowable Force [Fzmax]:

= fs * eac?* Max(C2, 1.81)

= 1536.294 * 23.000?* Max(2.040 , 1.81)

= 16582.230 kgf

Maximum Allowable Moment [MXmax]:

= fs * eac?* d / 4 * Max( C3, 4.90 )

= 1536.294 * 23.000?* 262.897 /4 * Max(4.914 , 4.90 )

= 2624.865 kgf-m.

Maximum Allowable Moment [MYmax]:

= fs * eac?* d/4 * Max( C4, 4.90 )

= 1536.294 * 23.000?* 262.897 /4 * Max(8.087 , 4.90)

= 4319.363 kgf-m.

Unity Check per PD:5500 per 3.4 for Simultaneous Loads:

P/Pmax = 0.104 Fz/Fzmax = 0.074 Mx/Mxmax = 0.233 My/Mymax = 0.184

Maximum Allowable Radial Force Fzmax, and Moments Mxmax, Mymax:

Determine the value of [LambdaC]:

= d /( D * eac )?

= 161.710 /(1329.000 * 23.000 )?= 0.925

From Figures 3.1, 3.2 and 3.3:

C2 = 1.485 C3 = 4.705 C4 = 5.682

Maximum Allowable Force [Fzmax]:

= fs * eac?* Max(C2, 1.81)

= 1536.294 * 23.000?* Max(1.485 , 1.81)

= 14709.842 kgf

Maximum Allowable Moment [MXmax]:

= fs * eac?* d / 4 * Max( C3, 4.90 )

= 1536.294 * 23.000?* 161.710 /4 * Max(4.705 , 4.90 )

= 1609.915 kgf-m.

Maximum Allowable Moment [MYmax]:

= fs * eac?* d/4 * Max( C4, 4.90 )

= 1536.294 * 23.000?* 161.710 /4 * Max(5.682 , 4.90)

= 1866.938 kgf-m.

Unity Check per PD:5500 per 3.4 for Simultaneous Loads:

P/Pmax = 0.094 Fz/Fzmax = 0.050 Mx/Mxmax = 0.137 My/Mymax = 0.154

P/Pmax + Fz/Fzmax + Mx/Mxmax + My/Mymax = 0.434
