Are you curious to know what is indicated power? You have come to the right place as I am going to tell you everything about indicated power in a very simple explanation. Without further discussion let’s begin to know what is indicated power?
Indicated power is a critical measure of the performance of internal combustion engines, and understanding this concept is essential for anyone working in the field of mechanical engineering. In this blog post, we will take a closer look at what indicated power is, why it is important, and how it is calculated.
What Is Indicated Power?
Indicated power is the measure of the amount of power generated by an engine during the power stroke of its combustion cycle. During this phase, the fuel-air mixture inside the engine’s cylinders is ignited, causing a rapid expansion of gases that drives the piston downward and generates mechanical work. Indicated power is calculated by measuring the pressure inside the engine’s cylinders during each stroke of the piston and using this data to calculate the amount of work done during the power stroke.
Why Is Indicated Power Important?
Indicated power is an important measure of the efficiency and performance of an engine, as it provides a direct measure of the amount of power that is being generated by the engine’s combustion cycle. By accurately measuring indicated power, engineers, and designers can evaluate the efficiency of an engine’s operation and make improvements to enhance its performance.
How Is Indicated Power Calculated?
Indicated power is typically calculated using a device called an indicator, which is attached to the engine’s cylinders and records the pressure inside the cylinder during each stroke of the piston. This data is then used to calculate the amount of work done during the power stroke. The formula for calculating indicated power is:
Indicated power = (Pmax x Vd x n) / (60 x 1000)
Where Pmax is the maximum pressure recorded by the indicator, Vd is the displacement volume of the cylinder, n is the number of power strokes per minute, and 60 x 1000 is a conversion factor that converts units from seconds to minutes.
Indicated power is a key metric used to evaluate the performance and efficiency of internal combustion engines. By understanding how indicated power is calculated and its importance in evaluating engine performance, engineers and designers can develop more efficient and effective engines that meet the needs of a wide range of applications.

What Is Indicated Power And Brake Power?
The difference between indicated power and brake power is as follows. First of all, by indicated power we mean GROSS indicated power, the total work done by the gas on the piston during compression and power strokes. The brake power is the power available at the dynamometer. The difference is called friction power.
What Is The Indicated Power Formula?
The power produced by each cylinder unit is given by P*L*A*N *2* π /60 kw., where : P is the mean effective pressure given in KN/M. L is the length of the stroke given in. A is the area of bore of each cylinder given in M2.
What Is The Formula For Indicated Power And Brake Power?
It is the ratio of brake power to indicated power. η m = B . P I . P = η b t h η I t h.
What Is Indicated And Brake Power Efficiency?
Explanation: Mechanical efficiency is defined as the ratio of brake power (delivered power) to the indicated power (power provided to the piston). It can be defined as the ratio of the brake thermal efficiency to the indicated thermal efficiency.
