Homework Statement "On a horizontal table without friction it's a cube of mass M=70 kg and on the cube it's a body of mass m1=1kg. The body m1 it's conected by a cord with an other body of mass m2=4 kg, situated at hight H=1,5 m above the table. The sistem starts from 0 velocity. What it's...

I'm curious as to why steam tables typically present liquid properties with an "f" subscript, such as ρf.The gas properties use a "g" subscript, so I would expect the liquid properties to use "l". My first guess at the meaning of the "f" would be that it means "fluid", but this wouldn't make...
