A) wind

B) steam

C) Gas

D) Nuclear

Answer - B

Rankine cycle MCQ - 12

Rankine efficiency of a steam power plant

A) improved in winter season

B) improved in summer season

C) improved in winter and summer season

D) Not improved in winter and summer season

Answer - A

Rankine cycle MCQ - 13

Rankine cycle efficiency is more than Carnot cycle

A) True

B) False

Answer - A

Solution

Rankine cycle efficiency is less than Carnot cycle because average temperature of heat added temperature in Rankine cycle is less than Carnot cycle so Rankine cycle efficiency is less than Carnot cycle.
