Question 122Steam Plants - QMED

The correct answer is B) Convert the potential energy of the supply steam to kinetic energy. The nozzle on a steam turbine is designed to convert the potential energy of the supply steam into kinetic energy. As the steam passes through the nozzle, its pressure decreases and its velocity increases, generating kinetic energy that can then be used to spin the turbine blades and produce mechanical power. The other answer choices are incorrect because they do not accurately describe the function of the nozzle. Option A is incorrect because the nozzle does not directly convert the steam's potential energy into mechanical energy. Options C and D are incorrect because the nozzle is not designed to convert kinetic energy back into potential energy or mechanical energy, respectively.
