The temperature of the radiator of the Carnot engine is 17°C. Its effectiveness is 40%. By what value must the temperature of the heater increase in order for the engine efficiency to increase to 50%?
Helium is used in the Carnot engine where the volumes beginning with
constant temperature heat addition are V,= 0.3565 m²; V,= 0.5130 m²; V3= 8.0
m³; V,= 5.57 m³. Determine the thermal efficiency. Use 1.66 as the specific
ratio of helium.
The efficiency of a Carnot engine is 29.3%. What is the temperature of the cold reservoir if the temperature of the hot reservoir is 425 K?
