Given that 10, 000cm3 of a fluid flows through a 2cm diameter pipe in 10min a. Find the rate of fluid flow in cubic meters per second.

b. Calculate the speed of the fluid in m/s.

c) Given that the temperature is 20◦C and the Reynolds Number per unit density is 1.060m3/kg, is the

fluid more likely to be glycerin or water? [Hint: find the viscosity of the fluid and then compare it

with that of the two fluids at 20◦C]

d) state whether or no the fluid is turbulent.

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
