Back Pressure in InstruCalc

Back Pressure in InstruCalc

(OP)
Dear All,

I got a calculation of Relief valve using InstruCalc Ver 5.1 from chemical engineer.

in the calculation there are input and output.
in the input, there is "Total Back Pressure = 30 kPag
and, in the output, there is "Max back Pressure = 60,89 kPag,

can anyone tell me the difference of that back pressure?

Thanks.
Akhmad
