I'm having trouble understanding what exactly a dimensionally correct equation is..here's my problem-
In the following expressions:
V-volume
A-area
P-pressure
p(lowercase)-density
t-time
m-mass
v-velocity
g-acceleration due to gravity
I'm supposed to state whether the following equations are dimensionally correct or incorrect, using the above variables in terms [L,M,t], the MKS system..
1. m/t=(3/2)pV/t
2. PV=(1/2)mv2+mg(V/A)
Can ANYONE explain to me if these are dimensionally correct or not and why?
