The bore diameter of each cylinder in a three-cylinder two-stroke petrol engine is 14.71 mm and the stroke length for each cylinder piston is 250.25 mm. During engine testing, the engine runs at 300 revolutions per minute (rpm) with a pressure-volume indicator diagram showing a mean net area of 6.8 cm² and area length of length of 2.6 cm. For a pressure scale of 350 kN/m² per cm on the indicator diagram, calculate the ndicated power developed by the engine. Give your answer in kilowatts (kW) to 2 decimal places. Pressure versus Volume Indicator Diagram (Pressure scale = 350 kN/m² per cm) Peak Pressure Enclosed net area for engine work done - m.e.p Diagram length, cm Diagram height, cm

Completely solve and box the final answers. Write legibly 9. A blower with the inlet open to the atmosphere delivers 250 cubic meters per minute of air at a pressure of 2.50 cm of water gage through a duct 25 cm in diameter, the manometer being attached to the discharge duct at the blower. Air temperature is 25 degrees C and the barometer pressure reads 1.025 bar. Calculate the required motor rating in KW if the blower efficiency is 92.5%
