Question

   Energy is sometimes expressed as v^1/2g althought this term doesn't have the units of energy. What are the units of this term and why would it be used to represent energy? Think about the fact that pgh represents the gravitional potential energy per volume of a fluid and that h is often used as a convenience unit for gravitational potential energy. Remember that 1/2 pv^2 represents the kinetic energy per unit volume where v is determined by v^2 = v.v and consider the case for which the fluid density is a constant

Explanation / Answer

   we know that units of velocity = m/s    Units of energy = J    The units of v / 2g = m/sec * sec2/m                               = sec    Therefore the units of v1 / 2g is not equalto energy.
