Complete Question
Air at 40C flows over a 2 m long flat plate with a free stream velocity of 7m/s. Assume the width of the plate (into the paper) is 0.5 m. If the plate is at a co temperature of 100C,find:
The total heat transfer rate from the plate to the air
Answer:
![q=1.7845](https://tex.z-dn.net/?f=q%3D1.7845)
Explanation:
From the question we are told that:
Air Temperature ![T_1=40c](https://tex.z-dn.net/?f=T_1%3D40c)
Length ![l=2m](https://tex.z-dn.net/?f=l%3D2m)
Velocity ![v=7m/s](https://tex.z-dn.net/?f=v%3D7m%2Fs)
Width ![w=0.5](https://tex.z-dn.net/?f=w%3D0.5)
Constant temperature ![T_t= 100C](https://tex.z-dn.net/?f=T_t%3D%20100C)
Generally the equation for Total heat Transfer is mathematically given by
![q=hA(T_s-T_\infty)](https://tex.z-dn.net/?f=q%3DhA%28T_s-T_%5Cinfty%29)
Where
h=Convective heat transfer coefficient
![h=29.9075w/m^2k](https://tex.z-dn.net/?f=h%3D29.9075w%2Fm%5E2k)
Therefore
![q=h(L*B)(T_s-T_\infty)](https://tex.z-dn.net/?f=q%3Dh%28L%2AB%29%28T_s-T_%5Cinfty%29)
![q=29.9075*(2*0.5)(100+273-(40+273))](https://tex.z-dn.net/?f=q%3D29.9075%2A%282%2A0.5%29%28100%2B273-%2840%2B273%29%29)
![q=1794.45w](https://tex.z-dn.net/?f=q%3D1794.45w)
![q=1.7845](https://tex.z-dn.net/?f=q%3D1.7845)
I think the answer would be A if its wrong I’m sorry

Answer: c) they have low genetic variability among them.
When a plant is grown for several generations of offspring of a plant, then there are some common things which are to be noted which are found similar in the offspring and in the parent of the offspring. The flowers and fruits and the time or season they come in are absolutely the same.
