A pressure drop occurs across both the moving and fixed blades of a reaction turbine as a result of the __________.

Question 1 of 27070

A pressure drop occurs across both the moving and fixed blades of a reaction turbine as a result of the __________.

🔍 Key Concepts

• Impulse vs. reaction turbines – where the pressure drop occurs in each type • How nozzles affect steam velocity and pressure • The role of blade shape (fixed and moving) in changing steam pressure and direction

💭 Think About

• In a pure impulse turbine, where does most of the pressure drop occur – in the nozzles or across the moving blades? Compare that to a reaction turbine. • Think about what happens to pressure when a fluid passes through a convergent or convergent-divergent nozzle: how do velocity and pressure change? • Ask yourself: in a reaction stage, do the fixed and moving blades simply redirect flow, or do they also accelerate it like nozzles?

✅ Before You Answer

• Verify which option correctly links a nozzle-like action to BOTH the moving and fixed blades in a reaction turbine. • Eliminate any choice that mainly describes features of an impulse turbine, where almost all pressure drop is in stationary nozzles only. • Check that the statement about thermal vs. pressure energy is physically consistent: does converting thermal to pressure always cause a pressure drop, or is that wording suspect?

Question 1 of 27070

A pressure drop occurs across both the moving and fixed blades of a reaction turbine as a result of the __________.

interstage diaphragms creating a nozzle effect in the steam flow

moving and fixed blades being shaped to act as nozzles

reversing blades causing a velocity drop with resultant pressure drop

conversion of the thermal energy to pressure energy always resulting in a pressure drop
