For each of the following generator design concepts, mention two important benefits and two important drawbacks:
(i) fixed speed, (ii)limited variable speed, (iii) various speed parcially scale, (iv) various speed full scale
2 }
benefits of limited variable speed :
> it include short-circuit protection, quiet operation, and high efficiency at a wide range of speeds (normally above 50%).
> Lesser the risk of motor damage during start up and stop.
drawbacks :
>> Motor Heating at low Speeds
>> Induced Power Line Harmonics
For each of the following generator design concepts, mention two important benefits and two important drawbacks:...

Question 3. Mention any four advantages each of the following terms (i) job shop production (ii) batch production (iii) mass production (iv) continuous production
Two diesel generator sets which are independent and design to operate continuously, in parallel, are each capable of supplying the full load requirements in a particular situation. If one diesel generator has a mean constant failure-rate of 9 fault per 104h and on the occurrence of each fault is out of service for a fixed time of 50h, and the other diesel generator has a corresponding failure-rate of 15 faults per 104h and an out of service time per fault...

Mention two important techniques for a financial analysis Exercise 1: The GAT company makes pants and the costs involved per unit are the following: Table 1: Information on unit costs Description Costs Direct materials. $ 3.00 Direct work 2.40 Variable general expenses 1.80 Variable marketing expenses 0.80 Total fixed marketing expenses were $ 26,000, while administrative fixed expenses amounted to $ 70,000 for the past year. The price of the pants was $ 20.00 each. 6. How is the...
Sketch four graphs wherein each graph describes your hypothesized relationship between the two variables examined in that portion of the experiment. Note that the other two variables will be held constant during that part of the experiment. Be sure to label the axes of your graphs. Part I: Pressure & Volume Part II: Pressure & Temperature Part III: Volume & Temperature Part IV: Pressure & Number of Molecules Constant Variable #1 Constant Variable #2 Independent Variable Dependent Variable Part I...
