Q2. Merge sort on infinite linklist
Ans. 
Merge sort cannot be directly applied to an infinite linked list due to its divide and conquer nature.
• Merge sort requires dividing the list into smaller sublists, which is not possible with an infinite linked list.

• One approach is to break the infinite linked list into finite chunks, sort each chunk using merge sort, and then merge the sorted chunks.

• Another approach is to use a different sorting algorithm that can handl...read more

Q3. What is straight length requirements for orifice flow element
Ans. 
Straight length requirements for orifice flow element ensure accurate measurement by allowing flow to stabilize before reaching the element.
• Straight length requirements typically range from 10 to 44 pipe diameters upstream and 5 to 22 pipe diameters downstream of the orifice.

• These requirements help prevent flow disturbances and ensure accurate measurement of flow rate.

• For example, if the pipe diameter is 4 inches, the ...read more
