Science KS4 Lesson 2: Energy, efficiency, power & circuits
Screen 2.1: Every site along the Thames Tideway Tunnel will include ventilation, to keep the Tunnel free from odours. At main ventilation points like Abbey Mills Pumping Station, fans will draw air though the Tunnel so all the air is replaced once each day.
Screen 2.2: The system needs the right fans connected in the right way, so this important feature performs to specification. What energy conversions happen in a fan like this?
Screen 2.3: It's important that the Thames Tideway Tunnel can be operated efficiently. This minimises costs and the effect on the environment, from using energy to operate fixed machinery like ventilation fans.
Screen 2.4: Electrical Engineers have to choose the right circuit to allow equipment to work properly and safely.
Screen 2.5: Electrical Engineers have to choose the right circuit to allow equipment to work properly and safely.
Screen 3: Engineers design safety into their systems and circuits.
