The ratio for the cross section areas of the
tube is = 0.449, the difference in the
pressures is Pi - P2 = dP = 27.5 Pa, and the
density of the fluid is 1.27 kgm.
Find the speed of the fluid near the right
hand end of the tube (i. e., find v2).
Answer in units of m/s.

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day

option number c is the right answer.
