Head pressure for liquid in a tank

Click For Summary
SUMMARY

The discussion focuses on calculating head pressure exerted by a liquid in an open tank with a specific gravity of 1.735 and a height of 10 feet. The correct calculation for head pressure in inches of water column (w.c.) is confirmed as 17.35 inches. Additionally, the pressure in PSI is calculated using the formula P = (specific gravity)(0.433)(height in feet), resulting in approximately 7.51 PSI. Clarification is provided regarding the terminology of head pressure and the distinction between feet and inches.

Did I answer this right ?

An open tank contains liquid with a specific gravity of 1.735. If the height of the liquid is 10 feet, how much head pressure (in inches w.c. (water column)) will it exert?
P= (10) (1.735)= 17.35

What is the pressure in PSI?
P= (1.735)(0.433)(10feet)= 7.51255

Are feet and inches the same? How about a liquid with a S.G. of 1.735 and water?

You got the pressure OK, but it appears you are a little hazy on what head in inches of water column means.

And it's 'question', not 'quesstion'.
