Answer:
V=33.66 m/s
Re>4000, The flow is turbulent flow.
Explanation:
Given that
Pressure difference = 50 mm of Hg
We know that density of Hg=136000
ΔP= 13.6 x 1000 x 0.05 Pa
ΔP=680 Pa
Diameter of tunnel = 200 mm
Property of air at 25°C
ρ=1.2
Dynamic viscosity
Velocity of fluid given as
V=33.66 m/s
Reynolds number
Re>4000,So the flow is turbulent flow.
