Concept Question:
From Bernoullis equation,
if you have point A and point B, where point A is at a higher elevation than point B, lets say Z1 and Z2 respectively -
You have a pump running the fluid from point B to point A , i.e. against gravity.
I understand the following:
Pressure losses, h, moves in the same direction as your flow, v, and your friction, f, moves opposite to your flow, always.
So the head loss AS A RESULT OF FRICTION from Z2 to Z1, will be negative or positive?
I assume negative, and the value of the aforementioned head loss will be positive in the bernoulli equation on the side of the equation involving A , as this is the direction the flow is moving towards.
Hence my question:
So the head loss AS A RESULT OF FRICTION from Z2 to Z1, will be negative or positive?

The pressure of the cerebrospinal fluid can be measured by means of a spinal tap. A hollow tube is inserted into the spinal column, and the height to which the fluid rises is observed. If the fluid rises to a height of 160 mm, we write its gauge pressure as 160 mm H2O.

In other cases, a physician may suspect that a tumor or other growth is locking the spinal column and inhibiting the flow of cerebrospinal fluid. Such conditions can be investigated by means of the Queckensted test. In this procedure the veins in the patient’s neck are compressed, to make the blood pressure rise in the brain.
