Answer:
A) True
Explanation:
Yes this is true when length is creases the heat transfer coefficient decease with length.
The heat transfer(h) coefficient is varying with x by given expression
For Laminar flow
[tex]h \alpha \dfrac{1}{x^{\frac{1}{2}}}[/tex]
For turbulent flow
[tex]h \alpha \dfrac{1}{x^{\frac{1}{5}}}[/tex]
But when flow is in transitional state the heat heat transfer(h) coefficient is increases with x.But for laminar as well as turbulent flow h is decrease when x increases.
