A triathlete is swimming at 1 m/s (relative to a fixed point on shore) against a current of 0.25 m/s in the opposite direction. What is the relative velocity of the triathlete with respect to the water

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.
