AI Generated Solution

To understand why a Carnot engine is referred to as an ideal engine, we can break down the explanation into several key points: ### Step-by-Step Solution: 1. **Definition of a Carnot Engine**: - A Carnot engine is a theoretical thermodynamic cycle that provides the maximum possible efficiency for a heat engine operating between two temperature reservoirs. It is based on reversible processes. 2. **Reversibility**: ...

Find the efficiency of a carnot engine whose source and sink are 327^(@)C and 27^(@)C ?

The efficiency of a heat engine is defined as the ratio of the mechanical work done by the engine in one cycle to the heat absorbed from the high temperature source . eta = (W)/(Q_(1)) = (Q_(1) - Q_(2))/(Q_(1)) Cornot devised an ideal engine which is based on a reversible cycle of four operations in succession: isothermal expansion , adiabatic expansion. isothermal compression and adiabatic compression. For carnot cycle (Q_(1))/(T_(1)) = (Q_(2))/(T_(2)) . Thus eta = (Q_(1) - Q_(2))/(Q_(1)) = (T_(1) - T_(2))/(T_(1)) According to carnot theorem "No irreversible engine can have efficiency greater than carnot reversible engine working between same hot and cold reservoirs". Efficiency of a carnot's cycle change from (1)/(6) to (1)/(3) when source temperature is raised by 100K . The temperature of the sink is-

Two ideal Carnot engines operate in cascade (all heat given up by one engine is used by the other engine to produce work) between temperatures, T_(1) and T_(2) . The temperature of the hot reservoir of the first engine is T_(1) and the temperature of the cold reservoir of the second engine is T_(2) . T is temperature of the sink of first engine which is also the source for the second engine. How is T related to T_(1) and T_(2) , if both the engines perform equal amount of work?

Cascaded Carnot engine is an arrangement in which heat sink of one engine is source for other. If high temperature for one engine is T_1 , low temperature for other engine is T_2 (Assume work done by both engine is same) Calculate lower temperature of first engine
