(28 points) In a little over 5 billion years, our star will slough off ~20% of its mass and collapse to a white dwarf star of radius 8,000 km. We will model it as a sphere. What will its angular momentum be in terms of its current angular momentum? What will its rotation period be in terms of its current period? b) (12 points) What will its rotational kinetic energy be in terms of its current rotational kinetic energy?

Air enters a compressor operating at steady state at 1.05 bar, 300 k, with a volumetric flow rate of 93 m3/min and exits at 12 bar, 400 k. heat transfer occurs at a rate of 15.5 kw from the compressor to its surroundings. assuming the ideal gas model for air neglecting kinetic potential energy effects, determine the power in put in kw.
