Answer:
Electroosmotic velocity will be equal to ![1.6\times 10^{-4}m/sec](https://tex.z-dn.net/?f=1.6%5Ctimes%2010%5E%7B-4%7Dm%2Fsec)
Explanation:
We have given applied voltage v = 100 volt
Length of capillary L = 5 mm = 0.005 m
Zeta potential of the capillary surface ![\xi =80mV=0.08volt](https://tex.z-dn.net/?f=%5Cxi%20%3D80mV%3D0.08volt)
Dielectric constant of glass is between 5 to 10 here we are taking dielectric constant as ![\epsilon =10](https://tex.z-dn.net/?f=%5Cepsilon%20%3D10)
Viscosity of glass is ![\eta =10^8](https://tex.z-dn.net/?f=%5Ceta%20%3D10%5E8)
Electroosmotic velocity is given as ![v_{eo}=\frac{\epsilon \xi }{\eta }\times \frac{v}{L}](https://tex.z-dn.net/?f=v_%7Beo%7D%3D%5Cfrac%7B%5Cepsilon%20%5Cxi%20%7D%7B%5Ceta%20%7D%5Ctimes%20%5Cfrac%7Bv%7D%7BL%7D)
![v_{eo}=\frac{10\times 0.08 }{10^8 }\times \frac{100}{0.005}=1.6\times 10^{-4}m/sec](https://tex.z-dn.net/?f=v_%7Beo%7D%3D%5Cfrac%7B10%5Ctimes%200.08%20%7D%7B10%5E8%20%7D%5Ctimes%20%5Cfrac%7B100%7D%7B0.005%7D%3D1.6%5Ctimes%2010%5E%7B-4%7Dm%2Fsec)
So Electroosmotic velocity will be equal to ![1.6\times 10^{-4}m/sec](https://tex.z-dn.net/?f=1.6%5Ctimes%2010%5E%7B-4%7Dm%2Fsec)
Answer:
Both Technician A and B are correct.
Explanation: A brake lathe is a special tool used to improve or work on the surface of brake pads it helps to smoothen the surface.
Brake lathe has been found to be very effective in removing rusts in rotors and unevenness in the brake pad surfaces in order to ensure the efficiency and effectiveness of the brake system of a vehicle. Hence, a brake lathe helps to make brake rotor surface as smooth as possible.
Answer:
Both Technician A and B are correct
Explanation:
Due to a contamination of the clutch disc friction surface, the clutch chatters
The contamination that causes clutch chattering includes
1) Worn or broken motor mounts
2) Bell housing bolts becoming loose
3) Clutch link damage
4) Warped flywheel, due to overheating, the flywheel can become warped such that the non uniform surface interfaces the clutch resulting in clutch chattering
5) Engine or transmission oil contaminating the disc.
