**1.I have been asked to:**

Calculate the density of a fluid if a ctitical velocity of 2m/s at Re=2000 in a pipe of bore 90mm at a dynamic viscosity oc 0.09cP

I have calcualted the variables to SI units and found

[tex]\rho[/tex]=?

Um (V) =2m/s

D=0.09m

[tex]\mu[/tex]=0.09X10^-3

I am rearranging this formula

[tex]\rho[/tex]= (Re*[tex]\mu[/tex])/(Um*D)

I keep getting 1 as the answer for the density. Have I converted something to SI units incorrectly?

Thanks.
