OK . . .What does a 5W-30 do that an SAE 30 won't? When you see a W on a viscosity rating it means that this oil viscosity has been tested at a Colder temperature. The numbers without the W are all tested at 210Â° F or 100Â° C which is considered an approximation of engine operating temperature.
(Answer #1). The Industrial Revolution was a time when the world's economy started to be more industrialized -- things came to be made in factories rather than by individual artisans. Great Britain took the lead in this largely because of geography.y about mid nineteenth century it took firm roots in western Europe and northeastern USA. The industrial revolution first developed in Great Britain for several reasons. The two most important of these are abundant supply of coal and iron and the economic advantages accruing to the country because of its colony.
Britain was the first site of the industrial revolution. Britain  became the workshop of the world through the Enclosure movement,  Textiles, Better Transportation, canals, â¦ railroads, ect. Many other  factors contributed to Britain success.s the size of cities increased, so did the demand for consumer products. As a result, entrepreneurs and inventors were more than happy to meet consumer demand. Once mass production was introduced, the Industrial Revolution was in full swing.
