Hello dear,
● Answer- 40 mm Hg
● Explaination-
# Given-
Mw = Mhg
Lw + Lhg = 29.2 cm
ρhg/ρw = 13.6
# Solution-
We have
Mw = Mhg
ρw.A.Lw = ρhg.A.Lhg
ρhg / ρw = Lw / Lhg
13.6 = Lw / Lhg
Lw = 13.6 Lhg
Also, Lw + Lhg = 29.2
13.6 Lhg + Lhg = 29.2
Lhg (13.6+1) = 29.2
Lhg = 29.2 / 14.6
Lhg = 2 cm = 20 mm Hg
As Mw = Mhg
Pw = Phg
P = Pw + Phg = 2 Phg
P = 20×2 = 40 mm Hg
Therefore total pressure will be 20×2 = 40 mm Hg.
Hope this is useful...
