Text Solution

AI Generated Solution

To find the efficiency of a Carnot engine working between the ice point and steam point, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Temperatures**: - The ice point corresponds to a temperature of 0°C, which is equivalent to 273 Kelvin (K). - The steam point corresponds to a temperature of 100°C, which is equivalent to 373 Kelvin (K). ...

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-
