Question

In the spin cycle of a washing machine, the tub of radius 0.299 m develops a speed of 652 rpm. What is the maximum linear speed with which water leaves the machine? Answer in units of m/s.

Answer 1

Maximum speed of water that leaves the machine is 20.5 m/s

Step-by-step explanation:

As we know that the angular frequency of the tub is

f = 652 rpm

so we have

`f = 10.87 rounds/sec`

now we have

`\omega = 2\pi f`

`\omega = 68.3 rad/s`

Now tangential speed is given as

`v = R\omega`

so we will have

`v = (0.299)(68.3)`

`v = 20.5 m/s`
