1. Reaction steam turbine
2. Velocity compounded impulse steam turbine
3. Pressure compounded impulse steam turbine
4. Pressure-velocity compounded steam turbine

Answer:(B) - Velocity compounded impulse steam turbine

## Curtis turbine is a velocity compounded impulse steam turbine

Solution:-

• In the Curtis turbine, a pair of moving and fixed blades are assembled after a nozzle.
• In the nozzle, pressure decreases, and velocity increases, so the enthalpy remains constant.
• In a moving blade, the kinetic energy of the fluid is used to convert mechanical energy; as the kinetic energy of the fluid is used, velocity gets reduced.
• The function of a fixed blade is redirecting the fluid leaving from 1st moving blade to the 2nd moving blade. In this, pressure and velocity remains constant
• Hence in the Curtis turbine, velocity is reduced and compounded by instating the fixed blade between two successive moving blades. So it is velocity compounded steam turbine
