Oil weight, or viscosity, refers to how thick or thin the oil is. The temperature requirements set for oil by the Society of Automotive Engineers (SAE) is 0 degrees F (low) and 210 degrees F (high).
Oils meeting the SAE's low temperature requirements have a "W" after the viscosity rating (example: 10W), and oils that meet the high ratings have no letter (example SAE 30). An oil is rated for viscosity by heating it to a specified temperature, and then allowing it to flow out of a specifically sized hole. Its viscosity rating is determined by the length of time it takes to flow out of the hole. If it flows quickly, it gets a low rating. If it flows slowly, it gets a high rating.
The length is 20cm and the width is 10cm P = 2l + 2w 60 = 2l + 2w 30 = l + w 30 = 2w + w 30 = 3w w = 10 30 = l + w 30 = l + 10 l = 20
Does this mean w^2 + w -30 = 0 ? If so, w = 5 or -6
If you mean 2/10 of 30 then it is 6
20
If you mean: 10+4r = 30 then it works out that r = 5
5 W 30 or 10 W 30
The length is 20cm and the width is 10cm P = 2l + 2w 60 = 2l + 2w 30 = l + w 30 = 2w + w 30 = 3w w = 10 30 = l + w 30 = l + 10 l = 20
Should probably use 10 w 30 or 30 w.
Sure but by doing that you change the viscosity slightly.
Does this mean w^2 + w -30 = 0 ? If so, w = 5 or -6
Should probably use 10 w 30 or 30 w.
