Surge Pressure Computations

Surge Pressure Computations

Surge Pressure Computations. What is a Surge. A pressure surge or a water hammer is a pressure wave caused by a sudden change in water velocity. The word “water hammer” originates from the hammering sound which plumbing makes inside a house when faucets are turned on or off quickly.

Vorticity

Vorticity

Vorticity. The Law of conservation of Vorticity. Relative vorticity is defined as The time rate of change of vorticity can be written by taking the equations of horizontal momentum and deriving the x component with respect to y and the y component with respect to x

Enduring Understanding

Enduring Understanding

Enduring Understanding. Energy transfer between the Earth’s surface and the atmosphere creates the weather. The atmosphere remains in balance until acted on by an outside force. Weather. Weather is the current state and short term variations in the state of the atmosphere

5.3 WEATHER FORECASTING

5.3 WEATHER FORECASTING. Air Movement. The movement of air caused by the differences in air pressure is called wind . The greater the pressure difference, the faster the wind moves. Air moves from areas of HIGH pressure into areas of LOW pressure. Air Movement.
