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

The Reynolds number is 5600.

Step-by-step 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)=(\rho V* 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)=(1400*1*2)/(0.5)`

`R_(e)=5600`

Hence, The Reynolds number is 5600.
