Question

Give me both right solutions with clear calculation 

2. Manometer is a useful device to measure the pressure for liquid tanks in industries. Figure 2
shows a water tank with a gauge pressure of the air being measured to be 65 kPa. Determine
the differential height h of the mercury column, when H1 = 20 cm, H2 = 71 cm. Note that SG is
denoted as specific gravity.
(a) Determine h value in cm.
(b) If the manometer liquid of Mercury is replaced by another liquid of a relatively smaller
density, explain whether h will increase or decrease.
