what is the difference between P=hdg and P=vdg. when and where should we use both of them.are the both same?
@ arun both formula are nearly same , both defines the formula for buyoncecy , the only thing that u need to understand is that we use h = pdg in the case of gas where volume expansion takes place , and we use p = hdg is the case of liquid expansion . HOPE IT CLEARS ..
P=hdg..This is the pressure exerted by a liquid column. Here P is directly proportional to h and d and not proportional to g.If density of a liquid is increased and if h is increased then P will also increase.P=vdg..we know upthrust=vpgupthrust=mass*g( v*p=m) =mg upthrust is force by water on body in upward direction. in this case P= vpg
