1. ## properties of supercritical fluids

Supercritical fluids have the properties: low viscosity of a gas. the high density of a liquid, making it impossible to liquefy the matter using any amount of pressure. ... Volatile liquids and solids, or liquids solids with a high vapor pressure or low boiling point, are soluble in gas. Bk
2. ## Jigs and fixtures

What are Fixtures? Fixtures are the work holding device which holds, supports and locate the workpiece but not guides the cutting tool to perform a specific operation. In other words the fixtures are only the work holding device that holds, supports and locate the workpiece in desried position to perform any operation. What are Jigs? Jigs are the work holding device which holds, supports and locate the workpiece and guides tools to perform a specific operation. In other words we can say that, jigs are the device which is used for both purposes of holding the workpiece and guiding the tool. I write more useful content on Difference between jigs and Fixtures
3. ## Frictional force produced by the rubber

The frictional forces generated between plastic, rubber and various hard surfaces are often represented with a simple coefficient of friction (COF) value yet in reality can be a function of material, surface finish, temperature, rate of relative movement, time and normal pressure..

4. ## Why is first angle method preferred over third angle ?

Difference between first angle and third angle first angle of projection: here object is placed in first quadrant it means object is placed in between the observer and the plane.what ever shape observed from the front u r going to project on the plane which is situated at back side of the object. third angle of projection : here object is placed in first quadrant it means plane is placed in between the observer and the object. what ever shape observed from the front u r going to project on the plane which is situated in front of the object.
