Given:

p1 + 1/2 (row) v1^2 = p2 + 1/2 (row) v2^2

On the left hand side of the equation, the first term, pressure must have units of force/unit area; say lb/ft^2. The units in the second term are the product of

row, the density in, say, lb/ft^3

v1^2, the square of speed, say, ft^2/sec^2,

or [lb/ft^3][ft^2/sec^2] = [ lb/(ft sec^2) ] and this is different from the [lb/ft^2] of the first term. Why?

Thanks
