Hello,

I have a homework due tomorrow and I don't understand some things, or even what some of the things mean.

1) this problem is about a pump, and I have to convert a pressure in psi to ft. The hint given to us shows multiplying by 2.31 but I don't know what 2.31 stands for.

it shows: ___ (psi) x2.31= ___ f(t)

I have some other problems but I want to try and solve them on my own, and if I have some problems then I can post here (hopefully)
