The net force acting on an object in the horizontal direction is 25 newtons, and the force acting in the vertical direction is 18 newtons. find the angle from the horizontal in which the force is acting.

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.
