The following observations were recorded during a trail of a four-stroke, single cylinder oil engine. Duration of trial = 30 min; oil consumed = 4 litres; calorific value of oil = 43 MJ/kg ; specific gravity of fuel = 0.8; average area of the indicator diagram = 8.5 cm²; length of the indicator diagram = 8.5 cm; Indicator spring constant = 5.5 bar/cm; brake load = 150 kg; spring balance reading = 20 kg; effective brake wheel diameter = 1.5 m; speed = 200 rpm; cylinder diameter = 30 cm; stroke = 45 cm; jacket cooling water = 10 kg/min; temperature rise of cooling water = 36 C. Calculate the: 3.1 3.2 3.3 3.4 3.5 3.6 Indicated power, Brake power, Mechanical efficiency, Brake specific fuel consumption, Indicated thermal efficiency, and Heat carried away by cooling water (2) (2) (2) (2) (2) (2) [12] The following observations were recorded during a trail of a four-stroke, single cylinder oil engine.
