Todayâs lesson is brought to you by 7, 14, and the letters. Kw, pH. Kw: the ion-product constant of water Q: will pure distilled water conduct electricity A: As the demo shows, it will (slightly). If water conducts electricity, ions must exist Water exists as an equilibrium, which is referred to as the self-ionization of water: H2O + H2O ï« H3O+(aq) + OHâ(aq) Kw What is the value of Kw?
Protecting Airport Personnel from. Lightning Strikes. L. ightning strikes are particularly. hazardous to ramp operations. at airports, where ramp workers. need to cease outdoor activities when. lightning presents an imminent danger. All aspects of airport operationsâ. landside, terminal, and airsideâ. are impacted when there is a ramp.
Figure 4: How lightning attaches to an airplane. Lightning is initiated at the airplaneâs leading edges, which ionize, creating a strike opportunity. Lightning currents travel along the airplane and exit to the ground, forming a circuit with the airplane between the cloud energy and the ground.
