Viscosity, Specific Gravity & Density

Click For Summary
SUMMARY

The discussion clarifies the relationships between viscosity, specific gravity, and density of fluids. Viscosity measures a fluid's resistance to shear deformation, while specific gravity is the ratio of a fluid's density to that of water. Density is defined as mass per unit volume. To calculate density, one can multiply the specific gravity by the density of water, providing a straightforward method for determining density from specific gravity.

What are the relationships between these 3 properties of a fluid and how would you calculate say the density when you know the viscosity and specific gravity?

Viscosity is a measure of "thickness" of the fluid. It's a resistance to shear deformation. Specific gravity is the ratio of the fluid's density over water's density. And density is just the ratio of mass to volume. To calculate density, just use the specific gravity and multiply by water's density.

Thread 'UV filter for home central heating?'

Had my central air system checked when it sortta wasn't working. I guess I hadn't replaced the filter. Guy suggested I might want to get a UV filter accessory. He said it would "kill bugs and particulates". I know UV can kill the former, not sure how he thinks it's gonna murder the latter. Now I'm finding out there's more than one type of UV filter: one for the air flow and one for the coil. He was suggesting we might get one for the air flow, but now we'll have to change the bulb...
