Q1Domain Verified
In the context of the Carnot cycle as presented in "The Complete Thermodynamics & Power Cycles Course 2026," which statement accurately reflects the efficiency of an ideal Carnot engine operating between two thermal reservoirs at temperatures $T_H$ and $T_L$?
Efficiency is given by $1 - (T_L / T_H)$, where temperatures are in absolute units (e.g., Kelvin).
Efficiency is independent of the reservoir temperatures and is always 100%.
Efficiency is determined solely by the working fluid's properties, such as its specific heat ratio.
Efficiency is directly proportional to the temperature difference ($T_H - T_L$) and inversely proportional to $T_L$.
Q2Domain Verified
Consider the Rankine cycle discussed in "The Complete Thermodynamics & Power Cycles Course 2026." If the boiler pressure is increased while keeping the turbine inlet temperature constant, how does this affect the cycle's thermal efficiency, assuming ideal components?
Thermal efficiency remains unchanged as the heat rejection temperature is constant.
Thermal efficiency increases because the average temperature of heat addition rises.
Thermal efficiency decreases due to increased pump work.
Thermal efficiency decreases due to increased heat losses in the boiler.
Q3Domain Verified
In the context of the ideal Otto cycle from "The Complete Thermodynamics & Power Cycles Course 2026," how does an increase in the compression ratio affect the thermal efficiency, assuming fixed heat input?
Thermal efficiency decreases because the maximum temperature reached during combustion is lower.
Thermal efficiency remains constant as the Otto cycle is a theoretical ideal.
Thermal efficiency decreases because the specific heat ratio of the working fluid decreases at higher temperatures.
Thermal efficiency increases due to a greater expansion ratio and more work output.
