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

Answer:
Suction and exhaust processes do not affect the performance of Otto cycle.
Explanation:
Step1
Inlet and exhaust flow processes are not including in the Otto cycle because the effect and nature of both the process are same in opposite direction.
Step2
Inlet process or the suction process is the process of suction of working fluid inside the cylinder. The suction process is the constant pressure process. The exhaust process is the process of exhaust out at constant pressure.
Step3
The suction and exhaust process have same work and heat in opposite direction. So, net effect of suction and exhaust processes cancels out. The suction and exhaust processes are shown below in P-V diagram of Otto cycle:
Process 0-1 is suction process and process 1-0 is exhaust process.
Answer:
A.
The power generated by a wind farm is not constant because of irregular wind patterns.
Disinfectant supplies, such as wipes of gel.
