🔍 Key Concepts

• Energy conversion in a gas turbine – how kinetic (velocity) and thermal (heat) energy of the gas interact with turbine blades • Action of gas on turbine blades – how the shape of blades turns straight gas flow into rotational motion • Difference between velocity increase/decrease and energy transfer to the rotor

💭 Think About

• When hot, fast-moving gas strikes turbine blades, what happens to the gas’s speed and direction, and where does that energy go? • Which choice best describes energy being taken from the gas and given to the rotor, rather than just changing the gas’s speed for its own sake? • In a working turbine, does the gas leave the turbine with more or less energy than it entered with, and what does that imply about the rotor?

✅ Before You Answer

• Identify which option talks about energy being passed from the gas to the blades/rotor, not just changing gas conditions by themselves. • Ask: in a turbine, is rotation produced mainly by creating a low-pressure area ahead of the rotor or by the gas doing work on the blades? • Check whether the option you pick would result in the gas losing energy while the rotor gains mechanical energy.

Question 1 of 20

How do the high-velocity high-temperature gases cause the gas turbine rotor to rotate?

By increasing the velocity of the gases.

By creating a low-pressure area before the rotor.

By transferring velocity energy and thermal energy to the turbine blades.

By converting the high-velocity gas to low-velocity gas.
