The specific kinetic energy of a moving mass is given by ke = V2/2, where V is the velocity of the mass. Determine the specific kinetic energy of a mass whose velocity is 200 ft/s, in Btu/lbm.

0.799Btu/lbm

Explanation:

Data given

velocity, v= 200ft/s

Since the formula to define the the kinetic energy is

where v=velocity and the final answer expressed in Btu/lbm

we just substitute the value of the velocity into the equation and we arrive at

Now we convert to Btu/lbm

since

then

Hence the kinetic energy in is 0.799Btu/lbm

the inner core.

good luck: )
