That's not what the text says: "Heat dQi enters at a particular part of the cycle." In the picture, it is represented by the solid arrow.Pushoam said:
So, heat enters only through that particular part of the process. For the rest of the part of the process, the heat doesn't enter the system from the reservoir. This is what I understood.DrClaude said:
I will take care of this from next time.DrClaude said:
That's not correct. Heat ##dQ_i## enters only during part ##i## of the cycle, but heat can enter at other places in the cycle, hence the sum over all the ##dQ_i## during the cycle.Pushoam said:
O.K.DrClaude said:
Work extracted from a general cycle is the amount of energy that is produced or gained during a thermodynamic cycle. It is the difference between the energy input and energy output of the system.
The work extracted from a general cycle is calculated by multiplying the force applied to move an object by the distance the object moves. In thermodynamics, it is calculated by taking the integral of the pressure-volume curve over the entire cycle.
The work extracted from a general cycle is an important measure of the efficiency of a thermodynamic system. It represents the useful work that can be obtained from a given amount of energy input.
Yes, work extracted from a general cycle can be negative. This occurs when the energy output is greater than the energy input, resulting in a net loss of energy. This is known as a heat engine or a refrigeration cycle.
The amount of work extracted from a general cycle is affected by several factors, including the type of cycle, the pressure and volume of the system, and the temperature at which the cycle operates. In general, a higher pressure and temperature will result in a greater amount of work extracted.
