Answer:
maximum flow speed is 5.278 cm/s
Explanation:
given data
temperature = 20°C
diameter d = 3.8 cm
density of water ρ = 1 × 10³ kg/m³
to find out
maximum flow speed
solution
we have given steam line flow so it is laminar flow
and for laminar flow we know reynolds number is Re= 2000
so
Re = [tex]\frac{\rho*v*d}{\mu}[/tex] ............1
here μ is dynamic viscosity = 0.001003 for 20°C for water
put all value in equation 1
Re = [tex]\frac{\rho*v*d}{\mu}[/tex]
2000 = [tex]\frac{1000*v*3.8*10^{-2}}{0.001003}[/tex]
solve it we get v
v = 0.0527 m/s
so maximum flow speed is 5.278 cm/s
