Which one is correct between:
1. MMSCFD ready to input:
, or the
2. CALCULATED MMSCFD from Stream Properties:


and what is the different on both of them? if the FIRST MMSCFD is at specified PT and not at STANDARD conditions, why don't it become MMCFD (MM Cubic Feet per Day) without S (Standard)?

I have an experience with it, i told to my senior that the correct one is the SECOND MMSCFD because it is the calculated MMSCFD at Standard Condition. but he told me that my understanding is wrong, so he order me to manually calculate the MMSCFD. and the result is yes my senior is right, the correct one is the FIRST MMSCFD. why was that? I don't know why Hysys keep showing 2 MMSCFD version in their fabulous software.
