Thank you Ben for your reply.
Could you tell me, what will be the wetted surface area of torispherical heads of a partially filled bullet?
Thanks in advance.
I want to size a safety valve for a vertical cylindrical styrene storage tank with torispherical heads. According to API-521, for fire case, Q=21000*F*(Wetted Area)^0.82. How to determine wetted area for the head. Can anybody please help?
