Two identical tubes have fluid flowing through them at the same speed. in one tube, the fluid is air, and in the other tube, the fluid is fresh water. density(kg/m^3) viscosity (pa⋅s)water at 20°c 998 1.002×10^−31air around 20°c 1.23 1.808×10^−51in which tube is viscosity more important? a. the tube with waterb. the tube with airc. viscosity is equally important in each tubed. not enough information given to decide

b. the tube with air

Explanation:

We know that Reynolds number given as

V=Velocity of fluid in the tube

μ=Viscosity of fluid

d=Diameter of the fluid

ρ=Density of the fluid

Re's lower value means that viscosity  is more significant for the fluid .Therefore tube with air is more important than the tube with water.

So the answer is --

b. the tube with air

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.
