Answer:

Explanation:
Given that

We know that
Rex=ρvx/μ
So


All other quantities are constant only x is a variable in the above equation .so lets take all other quantities as a constant C

We also know that
Nux=hx/K

m is the constant

This is local heat transfer coefficient
The average value of h given as


---------1
The value of local heat transfer coefficient at x=L

-----------2
From 1 and 2 we can say that

<u>Explanation:</u>
Task 1 time period = 200ms, Task 2 time period = 300ms
Task ticked =
→ 5 times
Task 2 ticked =
→ 3 times
At 600 ms → 200ms 200ms 200ms
300ms → 
Largest time period = H.C.M of (200ms, 300ms)
= 600ms
