Viscosity
The measure of the resistance of a fluid to flow is known as viscosity. Most fluids have some resistance to motion, the resistance provided by the fluid is called viscosity. This resistance is created by the force of attraction between the fluid molecules. If you pour water through a funnel, it flows easily and quickly, because it has very little resistance. But if you pour honey through a funnel, it may take a little time longer, as the density of honey is high.
Poiseuille's Law
The law of Poiseuille or Poiseuille's equation states that the pressure drop of an incompressible fluid especially a liquid in a laminar flow that passes through a cylindrical tube of length L, radius r, pressure gradient ΔP, and mainly depends on the viscosity of the fluid is nothing but the pressure difference of the layers of fluids. ΔP=P1-P2
Drag Forces
Forces that occur due to the movement of fluid are known as fluid mechanics. Following are the fluids present:
question 10
![A glass of iced tea contains a large chunk of pure ice partially floating on the iced tea. Given the density
of ice as 917 kg/m^3, and density of iced tea as 1008 kg/m^2.
8. Find the percent volume of ice that is floating above the water level.
9. Convert 2.5 atm into Pascal, lb/in^2, and kPa.
10. Seawater density is 1024 kg/m^3. A diver can only safely stand 5 atm when diving down. How deep
can he go down?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F12e6f1d1-a59b-426e-b55c-5778644eb2da%2F127f36b3-165e-40f4-91d9-49cc86d3edfd%2Fzp4lhbv_processed.png&w=3840&q=75)
