"pressure = hdg" is the only thing given
h= depth
d= density
g= gravity
The Attempt at a Solution
ive been trying to figure this out for days.... theres many ways to work it if we knew other numbers but i dont know how to get it from this without assuming water density, which unless im wrong is variable by temperature? we arent given a temp....
am i just blindly reading into this too much and its actually really simple?
1 thing though, PLEASE dont give me an answer, i just want a method, having an answer doesnt help if a similar question comes up in my exam.
