A multi-tube manometer using water and mercury is used to measure the pressure of air in a vessel, as shown in the Fig. For the given values of heights, calculate the gauge pressure (in kPa) in the vessel.
h1 = 0.4 m, h2 = 0.5 m,
h3 = 0.3 m, h4 = 0.7 m,
h5 = 0.1 m and h6 = 0.5 m.
Correct answer is 'Range: 193 to 195'. Can you explain this answer?

Starting from the right most limb and moving towards left most limb (adding and subtracting appropriate liquid columns.)
pair = ρmg(h6 + h5) − ρw g(h5 + h4) +ρmg(h4 − h3) − ρwg(h2 − h3) +ρmgh2 − ρwgh1
pair = ρmg(h6 + h5 + h4 − h3 + h2) −ρwg(h5 + h4 + h2 − h3 − h1)
pair = [13600 × (0.5 + 0.1 + 0.7 − 0.3 + 0.5) −1000 × (0.1 + 0.7 + 0.5 − 0.3 − 0.4)] × 9.81
pair = 194238 Pa Or 194.238 kPa
