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.
