If the rate of mass entering a control volume is different than the rate of mass leaving a control volume, can it be a steady process? If the rate of mass entering a control volume is the same as the rate of mass leaving a control volume, does it have to be a steady process? 3. A hose fitted with a nozzle results in a high velocity stream of water. If the water can be treated as incompressible, what can you conclude? Is this a steady or unsteady process? 4. Which do you prefer, flow work or flow energy? State your reason. If you think each are equally good descriptions, then come up with a way to show why there is flow energy in a way that would replace the discussion in the first part of section 5.2 5. 8.50 x 11.00in

Explanation / Answer

2) no..densiity is changing with time ;

3) yes.mass flow rate can be equal for steady flow only ;

4) steady process as liquid id incompressible ;

5) flow energy because flow also contains kinetic energy
