# Pressure and hydraulic head in an aquifer?

Here's a picture of the set up: http://tinypic.com/r/14tt2xc/7

The fluid in the standpipes is water.

What would the pressures be (in kPa) at point F and point A??

I think the pressure at F would be zero, if i'm not mistaken, but how would you calculate the pressure at A? (A is in line with the datum)

Also is the hydraulic head at point C 15m?

Thanks for any help!

P = rho x g x h

Pressure at F would be zero gauge pressure ( Atm pressure is acting)

Stand pipe is up to datum [A] in LHS figure?

Then the head will be 15 m at A [ If it is filled with water till bottom.]

1 meter of head = 9 804.139 432 pascal

Pressure at C would be 5 m head pressure.
