Question

Calculate the Reynolds number for a person swimming through maple syrup. The density of syrup is about 1400 kg/m^3 and the viscosity is about 0.5 Pa's. A person is about 2m in length and can swim about 1 m/s.

Answer 1

Answer:

The Reynolds number is 5600.

Explanation:

Given that,

Density = 1400 kg/m³

Viscosity = 0.5 Pa's

Length = 2 m

Speed = 1 m/s

We need to calculate the Reynolds number

Using formula of Reynolds number

$R_{e}=\dfrac{\rho V\times L}{\mu}$

Where, $\rho$ = density of fluid

v = speed of syrup

l = length of a person

$\mu$=Viscosity

Put the all value into the formula

$R_{e}=\dfrac{1400\times1\times2}{0.5}$

$R_{e}=5600$

Hence, The Reynolds number is 5600.
