The Correct Option is B
Solution and Explanation
Step 1: Define Impulse Machine.
In an impulse machine, the fluid dynamics are such that the enthalpy and pressure essentially remain unchanged across the rotor. The energy transfer occurs primarily due to changes in velocity or kinetic energy of the flow.
