Below, you are given an open tank system and a closed system with a wet lag. Find the min and max calibration span points $($inch WC$)$ of both systems are provided that $x=54"\text{'},Y={63}^{\text{'}\text{'}},Z={36}^{\text{'}\text{'}}$; the specific gravity of the process fluid is $0\mathrm{.}95,$ and the specific gravity of filling fluid is $0\mathrm{.}8.$
