Are Head Pressures in Two Different Wells Comparable?

[mathmanta]

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.
