1. Find the density of an oil filled in the liquid column as shown in figure. Given that absolute pressure at the bottom is 675 kPa , atmosphere pressure is 1.0132 bar. where \( X=4 m ; Y=4 m \), \( Z=1.75 \mathrm{~m} \).
(Enter only the values in the boxes by referring to the unit given in the bracket. Do not send the hand written answer sheets to my mail)
The density of the oil \( =\left(\right. \) unit in \( \mathrm{kg} / \mathrm{m}^{3} \) ) \( = \)
\( \square \)
