Q

Which of the effects listed describes the changes in the velocity and pressure of the steam as it passes through a nozzle?

🔍 Key Concepts

• Basic nozzle principle in thermodynamics and fluid flow • Relationship between pressure energy and kinetic energy (velocity) in a converging nozzle • How steam behaves when expanding through a restriction like a turbine nozzle

💭 Think About

• When a fluid like steam goes through a nozzle designed to accelerate it, what is the main purpose of that nozzle: to increase pressure or increase velocity? • If the fluid’s kinetic energy increases, where is that extra energy coming from in terms of pressure or potential energy? • Think about how a garden hose nozzle works: what happens to the speed of the water and the pressure within the jet as it exits?

✅ Before You Answer

• Recall that in a properly designed nozzle, the key function is to change pressure energy into velocity (kinetic) energy. • Consider the direction of energy conversion: does high pressure lead to low velocity, or low pressure to high velocity, when expanding through a nozzle? • Be sure you are thinking about the pressure inside the flowing steam in the nozzle, not the pressure of the supply line before the nozzle.
