Question

Steam nozzle converts

A.

Heat energy to kinetic energy

B.

Heat energy to potential energy

C.

Kinetic energy to heat energy

D.

Potential energy to heat energy

Answer ( Option A)

Heat energy to kinetic energy

Solution

The steam nozzle is a passage of varying cross-section by means of which a part of the enthalpy of steam is converted into kinetic energy as the steam expands from a higher pressure to a lower pressure. Therefore, a nozzle is a device designed to increase the velocity of steam. In simple words, steam nozzle converts heat energy to kinetic energy.

Hence, the correct option is (A).
