The following data refers for the single cylinder 4 stroke diesel engine. The brake power is 73 kW and engine speed is 500 rpm. The break mean effective pressure is 8 bar and mechanical efficiency is 80 %. The BSFC of the engine is .30 kg/kWhr of the fuel calorific value of 43200 kJ/kg. Determine indicated thermal efficiency.

A turbo generator rotating mass has a moment of inertia of 555 hyls/ m2. It is delivering 2500 kw at 1800 rpm. The load then suddenly increases to 2550 kw, the developed steam power remaining unchanged. What is the resulting speed in rpm after 10 seconds? 3311.381 3113.381 O 1133.381 O 1331.381

Design a five-liter car engine that operates on a four-stroke cycle. Decide what the design speed will be, and then give the number of cylinders, bore, stroke, piston rod length, average piston speed, imep, brake torque, fuel used, AF, and brake power, all at design speed. All parameter values should be within typical, reasonable values and should be consistent with the other values. State what assumptions you make (e.g., mechanical efficiency, volumetric efficiency, etc.)
