Answer and Explanation:
Some of the advantages of direct water supply system are:
- Smaller size of the cistern
- No risk of polluted water
- Ease of installation
- Lower pipe work
Some of the advantages of indirect water supply system are:
- It can be pumped completely
- Lower demand on the main source
- Minimization of wear and tear on taps
- Larger size of the cistern.

Explanation:
During rotor reconditioning, which is the process also known as machining and sanding, where sanding is the involves the application of between 120 and 150 grit sandpaper while using a non-excessive force that is applied non-directionally for up to 60 seconds on each side such that the surface roughness meets OE standards. The rotors are then cleaned by washing after they are serviced before they can then be installed.
Answer:
Explanation:
Once the centrifugal forces are equivalent as an object rotates, it is called "in equilibrium." If the point of impact of the moving object does not align with the center of the rotation, unequal centrifugal forces are produced and the rotating component is "out of equilibrium."
Two conditions for balanced condition are: static and coupled. Static equilibrium relates to a one plane mass in which the unit is balanced by weight inverse the unbalanced mass
formula used to calculate centrifugal mass is
where, m is mass, v is speed of body. r is radius
