WebQuestion: (2 points) In case of emergencies, a turbine is connected to an active steam pipe line using a valve. When the valve is opened, steam from the pipe line, which is initially at 450∘C and 8MPa, flows through the turbine into a 0.81 m3 tank, which is initially evacuated. WebMay 22, 2024 · In impulse turbines, the steam expands through the nozzle, where most of the pressure potential energy is converted to kinetic energy. The high-velocity steam from fixed nozzles impacts the blades, changes its direction, which in turn applies a force. The resulting impulse drives the blades forward, causing the rotor to turn.
