Which equation should be used to find the minimum required thickness of a boiler drum if the inside radius is given?

$t = PR SE-(l-y)P -c$

$t = PD 2SE + 2yP +c$

$t = PR SE-(l-y)P +c$ (correct)

$t = PR SE-(l+y)P +c$

Which equation should be used to find the maximum allowable working pressure (MAWP) of a boiler drum if the outside diameter is given?

$p = 2SE(t-C) D-2y(t-C)$ (correct)

$p = SE(t-C) R+(l-y)(t-C)$

$p = 2SE(t+C) D+2y(t+C)$

$p = SE(t+C) R+(l+y)(t+C)$
