What is work output in Otto cycle?

During the cycle, work is done on the gas by the piston between stages 2 and 3. Work is done by the gas on the piston between stages 4 and 5. The difference between the work done by the gas and the work done on the gas is shown in yellow and is the work produced by the cycle.

What is the formula of Otto cycle?

When we rewrite the expression for thermal efficiency using the compression ratio, we conclude the air-standard Otto cycle thermal efficiency is a function of compression ratio and κ = cp/cv.

What is the value of working fluid in Otto cycle?

9. What is the value of working fluid in otto cycle? Explanation: In air standard otto cycle working fluid is air. The specific heat ratio of air is equal to 1.4.

How do you calculate the power output of an engine?

The equation to calculate horsepower is simple: Horsepower = Torque x RPM / 5,252. You can use our horsepower calculator below to try it out yourself.

What is the formula for compression N ratio of the Otto cycle?

The air-standard Otto cycle thermal efficiency is a function of compression ratio and κ = cp/cv. It is a very useful conclusion because it is desirable to achieve a high compression ratio to extract more mechanical energy from a given mass of the air-fuel mixture.

What is the formula for compression ratio of the Otto cycle Mcq?

Explanation: This is the expression for efficiency of Otto cycle and rk=compression ratio=Vmax/Vmin.

What is the power output?

Power Output means the average rate of electric energy delivery during one Metering Interval, converted to an hourly rate of electric energy delivery, in kWh per hour, that is equal to the product of Metered Energy for one Metering Interval, in kWh per Metering Interval, times the number of Metering Intervals in a one- …

How do you calculate input and output power?

Input and output power

  1. Electrical power is calculated by multiplying voltage (in volts) by current (in amps).
  2. If a transformer is 100% efficient, then the input power will equal the output power.
  3. V P is input (primary) voltage.
  4. I p is input (primary) current.
  5. V s is output (secondary) voltage.

How do you calculate power output?

Power is equal to work divided by time. In this example, P = 9000 J / 60 s = 150 W . You can also use our power calculator to find work – simply insert the values of power and time.

How is compression ratio calculated?

Compression ratio formula It can be calculated according to the cylinder volume formula: Vd = b2 * s * π / 4 . Vc is the volume above the piston when the piston is at the top dead-centre (its topmost position), also called the compressed volume. b is the cylinder bore (diameter).
