A graduated cylinder has 33.5mL of water a piece of metal is added to the water and the new volume is now 47.2mL if the metal has a mass of 16.25g what is the density

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.
