Your answer is partially correct.

Pressure drop is a function of flow rate, length, diameter, and roughness. Either iterative methods OR equation solvers are necessary to solve implicit problems.

For a first guess of a $1$ ft diameter pipe, what is the fluid velocity?

$V=$ ft$/$s

What is the Reynolds number?

$Re=$

What is the pipe relative roughness?

$\frac{}{d}=$

$$

What is the friction factor?

$f=$

$$

What is the pressure drop for a $100$ ft length of pipe?

$p_2-p_1=$ psi

Is the first guess too large or too small?
