But what about water? Whether near freezing or just about to boil, water pours relatively the same. Honey when you heat it up: it immediately becomes easier to pour once it reaches a certain temperature also, when cooled, the consistency of honey thickens. Lubricants resembling this liquid are higher viscosity oils. This is because honey is more viscous than water and has a much higher viscosity.Īlternatively, this fluid is a great deal thicker - somewhat like honey. Immediately - but a glass of honey would slowly spill over, giving you a second to react. If you were to knock over a glass of water, the liquid would spill out Take, for example, this comparison of two common substances with different viscosities: water and honey. In a nutshell, the thicker the fluid is, the more resistance to flow it will demonstrate. Viscosity is the measure of a fluid's resistance to flow (under certain conditions). This liquid's water-like state is reminiscent of a lower-viscosity lubricant. Viscosity and though the word may sound a bit dense, it's actually pretty simple: it is a number value for the relative thickness (or weight) of your oil or lubricant. These numbers are representative of a lubricant's Numbers in 5w-20 might signify? Or - should you work with machinery that requires an industrial lubricant - the AW-68 on your pail of hydraulic oil? If you've changed your own oil before, then chances are you know what the "w" in 5w-20 means (HINT: it stands for winter grade, or rating).
