Answer 2

Given:

if the life-bearing is 144 millions of revolution and it is expected to give service for 8000 hours

To Find:

calculate its speed

Solution:

It is given that the life-bearing is 144 millions of revolution and it is expected to give service for 8000 hours and we need to find the speed of the same which can be calculated by dividing the number of revolutions by number of hours,

Number of revolution=144000000

Number of hours=8000

So the speed will be,

[tex]Speed=\frac{144000000}{8000} \\ =18000 rev/hr[/tex]

So the speed is 18000 revolutions per hour.

Hence, the speed is 18000 Rev/Hr.
