Are Head Pressures in Two Different Wells Comparable?

AI Thread Summary
Head pressures in two wells can be compared by calculating the weight of the water columns based on their respective depths and static water levels. In the case of Well 1, with a depth of 480 ft and a static water level of 160 ft, and Well 2, at 720 ft with a static water level of 560 ft, the pressures can be analyzed using hydrostatic pressure formulas. The discussion raises the question of whether the head pressure can be considered the same within a 10% margin. It also posits that increasing Well 2's depth to 1100 ft, while keeping the water bearing strata and static water level constant, would not affect the head pressure comparison. Calculating the water column weights will provide clarity on these points.

Hiya,

Hope this is the right section - I didn't see a hydrology section.

I'm presenting this like a homework question, but its more for a conversation at my office.

There are two wells. The water in the two wells is the same (no density difference etc... - but that doesn't mean it's "fresh" water)

Well 1: This well is 480 ft deep and the static water level is 160 ft. The water bearing strata is at 480 ft. The casing is 6" I.D.

Well 2: This well is 720 Ft deep and the static water level is 560 ft. The water bearing strata is at 720 ft. The casing is 10" I.D.

What formula could I use for:

Q1:

Is the head pressure the same (within 10%) between the two wells?


And, is this true or false:

Q2:

If well 2 was 1100 ft deep, but the water bearing strata was still 720 Ft and static water level is 560 ft, the result does not change.

Ideas?

Hmm...

Well (pun), I guess for now I will simply calculate the weight of the water columns and see if they are the same.
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
