Whoever gave Paul L a thumbs down has no idea of pressure.

All I'm asking is "What is the Pressure"
Pressure = Weight divided by Area.

= 100/¼ = 25 pounds per ¼in²
= 400psi

Now you've got me all cocked up.
100 lbs acting on an area of ¼in²
= 100 pounds per ¼in²
= 100 x 4 = 400psi.

400 pounds per sq inch?
The wording is ambiguous . The Q says that a weight of 100lbs is ACTING on 1/4" squared. It doesn't say what the quantity of water is. For all I know there could be 10,000 gallons. Incidentally I totally agree with you about head of water being the all important thing. I am a plumbing and heating engineer.

That 100 lbs of water is sitting on an area of 1/2*1/2 square inches. That area is 1/4 in^2 so the pressure is 400 psi. Paul L is right, Roundthr… is wrong.
