Entropy

In physics, entropy means the amount of disorder or the degree of randomness associated with a thermodynamic system. The system is not self-organized when the entropy of the system is high. For instance, when a system is at an elevated temperature, its molecules are in random motion, vibrating and colliding with each other. During this scenario, the probability of finding a molecule at a particular place twice, is low. Under this circumstance, the system can be said to be in a high entropy.

The arc length voltage characteristic of a DC arc is given by the equation V=24+4L where 'V' is the arc voltage in volts and L' is the length in mm. The static volt-ampere characteristic of the power source is approximated by a straight line with no load voltage of 80V and the short circuit current of 600A. Then the optimum arc length is (mm).
b) The bore of each cylinder in a four-cylinder four-stroke internal combustion engine is 28 mm and the stroke of each piston is 125 mm. During testing, the engine runs at 105 revolutions per minute (rpm) with a pressure-volume indicator diagram showing a mean net area of 2.4 cm2 and a diagram length of 0.9 cm. The pressure scale on the indictor diagram is set to 120 kN/m2 per cm. Calculate the mean effective pressure (m.e.p) and the indicated power developed by this four-cylinder four-stroke engine.
