Answer:
Planned maintenance refers to any scheduled activity carried out to check a machine is working ok and diagnose procedures to fix it if need it. On the other hand, predictive mainteance is all the techniques which help to define if a machine requires or not maintenance activities so far.
Explanation:
Planned maintenance is based on preventive routines to ensure a machine is working in acceptable conditions and at the same time prevent them to change to risky values performing acticities like parts replacement, cleaning, etc. The key of this maintenance is schedule, that is to say, is a maintenance that has to be carried out constantly each certain time. Predictive maintenance is different because it is used to define if a machie needs any kind of inspection or if, on the contrary, the machine can continue operating without any intervention. The good point about predictive maintenance is the capability of telling when a maintenance is required and when is no necessarily required which is ideal to save costs.
Answer:
<em>55%</em>
Explanation:
hot reservoir = 1100 K
cold reservoir = 500 K
<em>This is a Carnot system</em>
For a Carnot system, maximum efficicency of the system is given as
Eff = 1 - 
where Tc = temperature of cold reservoir = 500K
Th = temperature of hot reservoir = 1100 K
Eff = 1 - 
Eff = 1 - 0.45 = 0.55 or<em> 55%</em>
Answer =
dial bore gauge
a “dial bore gauge” measures the inside of round holes, such as the bearing journals . can mesure up to 2” and 6” diameter holes .
when ( “ ) is next to a number it means inches fwi - but hope this helped have a good day :)
Answer:d
Explanation:
(d) chain drive belt drive gear drive
Solution :
Given :
Operation time, 
= 3000 hours per year
Operation time, 
= 2000 hours per year
The density, ρ = 
The wind blows steadily. So, the K.E. = 
The power generation is the time rate of the kinetic energy which can be calculated as follows:
Power = 
Regarding that 
. Then,
Power 
→ Power = constant x 
Since, 
is constant for both the sites and the area is the same as same winf turbine is used.
For the first site,
Power, 
For the second site,
Power,
