Question

To what height should a cylindrical vessel of radius be filled liquid force curved equal bottom

Answer 1

Answer:

Explanation:

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.
