Consider two different fluids flowing in a round tube of length 1 m and
diameter 5mm. Calculate the Reynolds Number for each of the fluid
and establish whether the flow is Laminar or Turbulent.
L = 1 m.
Flow
D = 5 mm
Figure Q4 (b)
(1)
Air (kinematic viscosity, v = 1.79 × 105 m²/s at 50°C) with a
speed of 12 m/s and
(ii)
Water (p = 1.14 x 10-3 N s/m? at 15°C) with a mass flow rate of 8
g/s.
(iii)
Justify the reason for increase in viscosity of gasses with
increase in its temperature.
