WebThe formula of the fuel power is given by, Fuel Power = . mf × Cv m. f × C v Where, . mf m. f = Mass flow rate of the fuel Cv = Calorific value of the fuel Now the indicated thermal … Brake-specific fuel consumption (BSFC) is a measure of the fuel efficiency of any prime mover that burns fuel and produces rotational, or shaft power. It is typically used for comparing the efficiency of internal combustion engines with a shaft output. It is the rate of fuel consumption divided by the power produced. In traditional units, it measures fuel consumption in pounds per hour divided by the brake horsepower, lb/(hp⋅h); in SI units, this corr…
WebMay 22, 2024 · Thermal Efficiency Formula As a result of this statement, we define the thermal efficiency, ηth, of any heat engine as the ratio of the work it does, W, to the heat input at the high temperature, Q H. The thermal efficiency, ηth, represents the fraction of heat, QH, that is converted to work. The brake thermal efficiency for the engine is given by, ηBrakeηBrake = Brake powerFuel powerBrake powerFuel power Where the fuel power is the product of the fuel mass flow rate and the calorific value. Hence, ηBrakeηBrake = Brake power.mf×CvBrake powerm.f×Cv See more The brake thermal efficiency is the kind of engine thermal efficiencywhich is the ratio of the brake power at the engine crankshaft to the power generated by the combustion of the fuel.
