Answer:
8 poles
Slip= 16.67%
Explanation:
We use the formula for synchronous speed,
Where f is the frequency and p is the number of poles
Since frequency is given as 80 Hz and the motor speed also given as 1000 rpm then making p the subject of the above formula we get
By substitution
To find the slip, we now use the actual and since we know that and p=8 then
The motor speed is now
To find slip, we use the formula
Then by substitution
Therefore, slip=16.67%
Answer:
Purple without gray part is (80,0,80)
Explanation:
Faded purple is represented by the rgb values (130,50,130), that is to say, 130 red, 50 green and 130 blue. Now we need to remove the gray part which is represented by rgb values (50,50,50). Removing it from the faded purple is carried out by subtracting 50 from each one its rgb values. That is to say the the color without the gray part would be (80,0,80). Attached you will see both purple colors with their respective rgb values.
Answer:
Explanation:
Given
Distance between Plates(dy)=1 cm
Relative Velocity(du)=10 cm/s
Dynamic viscosity
We know shear stress is given by
where du=relative Velocity
dy=Distance between Plates
