According to the given text, what is the formula for calculating the thickness of a cylindrical vessel?

$t = 5PL^{4.8}Sw$

$t = 2.250MPa imes 1067mm$

$t = PL - 2Sw - 0.2P$

$t = A^{4.8}Sw$ (correct)

What is the value for the shell thickness calculated using the formula from PG-27.2.2?

17.86 mm

5 x 2.250 MPa x 853.6 mm

2400.75

10.63 mm (correct)

What is the minimum required thickness of the dished head according to PG-29.6?

112 MPa

10.63 mm

17.86 mm (correct)
