"Compute the flow time, tardiness, and lateness for each job, and the average flow time, average tardiness, and average lateness
for all jobs using the following sequences: SPT sequence, EDD sequence, and the sequence 4-2-5-1-3. Use minus sign to enter negative lateness values, if any. If your answer is zero, enter "0". Round your answers for the average values to two decimal places.'
1 answer:
Answer:
See explaination
Explanation:
SPT is recommended. It minimizes average flow time and number of jobs in system. Note that the last sequence based on common sense or random sequencing is the worst performer on all criteria, so the job sequencing rule does make a significant difference in insurance firm performance.

Answer:
The correct answer is option 'a': 0.046 meters.
Explanation:
We know that the exit velocity of a jet of water is given by Torricelli's law as
where
'v' is velocity of head
'g' is acceleration due to gravity
'h' is the head under which the jet falls
Now since the jet rises to a head of 90 meters above ground thus from conservation of energy principle it must have fallen through a head of 90 meters.
Applying the values in above equation we get the exit velocity as
now we know the relation between discharge and velocity as dictated by contuinity equation is
Applying values in the above equation and solving for area we get
The circular area is related to diameter as
Thus the diameter of the nozzle is 0.246 meters
