A working fluid enters a steady flow system with a velocity of 30m/s and leaves at 140m/s. The mass flow rate is 9 kg/s. The properties of the fluid entry are 13.8 bar,

0.122 m3

/kg, and internal energy 42.2 kJ/kg, and exit properties are 1.035 bar, 0.805

m3

/kg and internal energy 208 kJ/kg. Determine the work transfer in kW from the

system

During your summer internship for an aerospace company, you are asked to design a small research rocket. the rocket is to be launched from rest from the earth's surface and is to reach a maximum height of 910 m above the earth's surface. the rocket's engines give the rocket an upward acceleration so it moves with acceleration of 16.0 m/s2 during the time t that they fire. after the engines shut off, the rocket is in free fall. ignore air resistance.
