Explain the term coefficient of friction. On what factors does this coefficient depend?

Co - efficient of friction :

Loss of head due to friction in pipe is

$h_f = \frac{4fLv^2}{d \times 2g}$

here, the value of co-efficient of friction, (f) should be known accurately for predicting the loss of head due to friction in pipes.

On the basis of dimensional analysis, it …
