$p = \gamma h$
(a) the column is 1.37 m of water
$p = 9.81(1.37)$
$p = 13.44 \, \text{kPa}$ answer
(b) the column is 1.37 m of oil (sp gr 0.90)
$p = 0.90(9.81)(1.37)$
$p = 12.10 \, \text{kPa}$ answer
(c) the column is 1.37 m of mercury (sp gr 13.6)
$p = 13.6(9.81)(1.37)$
$p = 182.78 \, \text{kPa}$ answer
(d) the column is 1.37 m of molasses (sp gr 1.5)
$p = 1.5(9.81)(1.37)$
$p = 20.16 \, \text{kPa}$ answer
