The predicted out-of-sample time series are compared to observed precipitation anomalies using the correlation coefficient (Cor) and mean absolute error (MAE). The models are ranked separately based on Cor (RankCor) and MAE (RankMAE), and an average rank is calculated using a weighted formula...
Coefficient of Rolling Friction: 0.015 Tire Type: Truck tire Coefficient of Rolling Friction: 0.006 - 0.01 Tire Type: Train wheel Coefficient of Rolling Friction: 0.001 Let's figure out how much force a typical car might use to push its tires down the road. Let's say our car weighs 4,00...
How to use the chilled drink calculator? As we mentioned, the chilled drink calculator aims to work out the time a beverage requires in the fridge (or another cool place) to reach its optimal drinking temperature. However, with the aim of providing a more comprehensive service, we designed ...

Pilots have to do more than guide a plane through takeoff and landing though. They have to steer it through the skies, and airfoils and their flaps can help with that, too. The Lift Coefficient In determining the lift of a given airfoil, engineers refer to its lift coefficient. This numbe...

That meant it wasn't necessary to build flapping wings in order to fly. Instead, humans needed enough power and the right kind of wing construction. Scientists needed better investigative tools to work out those important questions. Wind tunnels were the answer. On the next page, you'll find...
The shelf life of pre-treated materials ranges from hours to years, depending on the plastic, its formulation, how it was treated and its exposure to elevated temperature after treatment. Material purity is the most important factor. Shelf life is limited by the presence of low molecular weight...
To manage this potential problem, a device such as theSETP0805-100-SEsetP positive temperature coefficient (PTC) temperature indicator helps protect USB Type-C plugs from overheating. It has been designed to accommodate the unique specifications of this USB standard and is capable of helping to ...
Then, using the known data for the fluids or gases to be heated or cooled, the energy balance of the process can be checked. Normally the customer defines the product’s flow rate and the desired entry and exit temperature. They will indicate the type of serviced fluid to be used and de...
