A mass of 9 kg of gas with an internal energy of 1908 KJ is at rest in a rigid cylinder. A mass of 1.0 kg of the same gas with an internal energy of 95.4 KJ and a velocity of 30 m/s flows into the cylinder. In the absence of heat transfer to the surroundings and with negligible change in the center of gravity, find the internal energy of the 10 kg of gas finally at rest in the cylinder. The absolute pressure of the flowing gas crossing the control surface is 0.7 MPa, and the specific volume of the gas is 0.00125 m^3/kg.
