How does the thermal efficiency of an ideal Otto Cycle change with the compression ratio of the engine and the specific heat ratio of the working fluid?
The answer is 38.
What do you mean by the term mechanical efficiency of an engine?
It is the ratio of indicated power to brake power.
What is the ratio of the energy a machine delivers to the energy supplied to it?
efficiencyThe ratio of useful energy to total input energy is called efficiency. It refers to the percentage of the work input that is converted to work output.
What is the ratio of a boiler burner indicates the flexibility of the burner to cope with variations of boiler load without losing efficiency of atomisation?
turndown ratio
Define reflux ratio?
reflux ratio is the ratio of the quantity of distilled material returns to the column to quantity of distillate. One can operate the distillation column without calculating reflux ratio, but the main purpose of it is to improve the efficiency of the distillate.
How does compression ratio affect engine efficiency and performance?
Engine efficiency is increased though compression ratio by allowing a more thermodynamic energy to be converted into mechanical energy. Energy transfer is the key to efficiency.
What is cutoff ratio?
Cutoff ratio is not the ratio of the volume of the cylinder at the end of combustion to the start of the combustion process in a diesel engine. actually cutoff ratio means point at which fuel injected for a period and fuel delivery is stopped at required instant -is called cutoff ratio.............
What is thermal efficiency?
Thermal efficiency is the efficiency of a heat engine measured by the ratio of the work done by it to the heat supplied to it.
What is the definition of thermal efficiency?
the efficiency of a heat engine measured by the ratio of the work done by it to the heat supplied to it.
With increasing temperature of intake air IC engine efficiency?
as intake air temperature increases it lead to decreas in i.c engine efficiency. as engine efficiency is ratio of difference in intake and outlet temperature to intake temperature.
How does the thermal efficiency of an ideal Otto Cycle change with the compression ratio of the engine and the specific heat ratio of the working fluid?
The answer is 38.
In case of si engine to have best thermal efficiency the fuel air mixture ratio should be what?
LEAN
What is an efficiency ratio?
The efficiency ratio for a machine usually refers to the ratio of the useful energy available from a machine and the energy put into it.
What is the compression psi of a compression ratio of 16.2?
There is no direct connection between compression ratio and pressure. Ratio is a mathematical calculation of the cylinder volume from bottom center to top center. Actual cylinder pressure will depend on the volumetric efficiency of the engine. Factors the affect volumetric efficiency include rpm, intake design, throttle plate size, amount of restriction in the exhaust, size of the valves, shape of piston and combustion chamber.
What are the factors that can affect the transfection efficiency and how?
seeding density of the cell quality of transfecting dna ratio of dna to transfectant reagent
If run the car 45mill per hour haw meany revolutions have to do?
Would depend on rear end gear ratio and transmission gear ratio. Torque converter efficiency and whether or not it is a "lock up" style would also affect engine rpm for any given cruise speed.
How inefficiencies of compressor and turbine affect back work ratio and efficiency of gas turbine?
Inefficiencies in the compressor of a gas turbine cycle increase the back-work ratio and decrease the thermal efficiency of the gas turbine cycle, since they increase the compressor work.
