Hi there! I have attached an example problem from my thermodynamics text book, and I understand everything except part (c) m( h + ke ) = m(c p T + V^2/2) where Cp is multiplied by 1000 (or ke/1000 as shown in solution.) why is this part done? I cannot figure it out at all. I see that it is to get the answer in terms of watts rather than kW, but I feel like I am missing something conceptually. In the following step when KE is ignored, it is not done... Any clarification would be greatly appreciated. Thanks! Heres the original question if additional context is needed: Air flows steadily in a pipe at 300 kPa, 77°C, and 25 m/s at a rate of 18 kg/min. Determine (a) the diameter of the pipe, (b) the rate of flow energy, (c) the rate of energy transport by mass, and (d ) the error involved in part (c) if the kinetic energy is neglected.
