For pressurized flow in a pipe with a constant diameter, the slope of the EGL will be

the slope of HGL$.$

$($a$)$ Steeper than

$($b$)$ Equal to

$($c$)$ Shallower than

$($d$)$ Not enough information

Pressurized flow in a pipe undergoes a sudden contraction. Following the contraction,

the distance between the HGL and EGL

$($a$)$ Increases

$($b$)$ Decreases

$($c$)$ Stays the same

$($d$)$ Not enough information

For flow in a pressurized pipe, which of the following changes will increase the head

losses? $($Assume changes are independent of one another, and circle all that apply$).$

$($a$)$ Increase flow velocity

$($b$)$ Increase pipe diameter

$($c$)$ Install an inline valve

$($d$)$ Increase pipe length

$($e$)$ Install a bend in the pipe

$($f$)$ Increase pressure while keeping constant flow rate
