The Netherlands has just unveiled a wave generator machine that can produce the world's largest human made wave. It was built at a facility in Deltares to test the structural plate and other barriers designed to stop waves whipped by the sea and violent storms.
Formulators generally apply two strategies that are complementary while defining product performance targets. The first strategy works towards altering the composition of the formulation whilst the second changes the physical characteristics of the constituents.
In formulations containing polymers the polymer concentration and molecular weight are the two variables that are altered most. However, there are numerous factors other than those that affect the polymer behavior. Some of these characteristics are temperature, polymer charge and solvent quality as well as the type and structure of the polymer.
Typically, formulation is an empirical process that is performed by altering the formulation and examining the impact of the changes through the measurement of product performance. This method is time consuming and does not provide an understanding of the correlation between the change and the observed effect. Also, correlating the test results with a measurable difference in the various grades available may be difficult. Formulations done this way do not provide substantial information for refining the choice of ingredients.
Now that the wing skinning is complete, the four outboard tanks can now be permanently installed. The fuel capacity is 205 gallons total for each outboard wing, and there is a 95 gallon tank in each side of the center section, giving a total fuel capacity of 600 U.S. gallons. All of the fuel feed and fuel vent lines, along with the cross-feed check valves are now permanently installed along with the electrical conduits and internal wiring that run through or near the fuel tank bays, i.e. boost pumps (four) and liquidometers (six).
