A student standing on a roof throws a ball toward the sky. He then tries to make an energy transfer diagram for the ball What
should go in the blank in the diagram?

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.

In order for the bug to fly through the air a force has to push the bug forward. identify this force. how does the bug produce
