Determine the condition of steam at a pressure of 10 bar and temperature of 200 ℃.
A gas initially at 510 kPa and volume of 142 liters undergoes a certain process after which the pressure and volume reach to 170 kPa and 275 liters respectively. And there is enthalpy drop of 65 kJ. The specific heat at constant volume for this gas is 718 J/kg-K. Calculate:1. Change in internal energy 2. Specific heat at constant pressure 3. Gas Constant.
Calculate the air standard efficiency of the diesel cycle where the pressure and temperature at the beginning of compression process are 1 bar and 27 ℃ respectively. The compression ratio is 14 and the constant pressure heat addition continues up to 7% of the stroke volume. Draw this Diesel cycle on p-v diagram.
Calculate the air standard efficiency of an Otto Cycle engine having a bore of 100 mm and stroke length equal to 150 mm. The clearance volume of cylinder is equal to 250 cm3. Take ᵞ = 1.4.
A Diesel engine develops 5 kW brake power at a speed of 1000 rpm. The mechanical efficiency of the engine is 75% and indicated thermal efficiency is equal to 30 %. The diesel fuel having specific gravity =
