Wind shear

BSS viscosity measurement, shearing was applied using spindle V-73 at a speed of 1, 2, 3, and 4 rpm. Viscosity measurement was conducted using Brookfield Viscometer (ASTM D4402). In this test, the viscosity, torque, and shear stress are determined while applying a rotational shear on the specimens. To prepare specimens, 10.5 grams of 90 bitumen scrap shingle sample was poured into aluminum chamber. The thermoset was preheated at its designated temperature for 45 minutes. Samples and the spindle…

In particular, B, G, and E of hexagonal structure are expressed as follows [34]: where B, G, and E are bulk, shear, and Young’s modulus, respectively. The resultant elastic constants, bulk, shear, and Young’s modulus are summarized in Table 2. Here, it can be seen that the B, G, and E are increasing with increasing amount of Si on the A site. This could be attributed to the charge density shown in Table…

but not as much as a supercell. Small sized hail, flash floods and even weak tornadoes can occur. Multi celled storms form a line of storms another name for those line of storms is called a Squall line. These squall can potentially have very strong winds, There known to have gusts exceed 70 mph. Multi cell storms like to form in air that is moist and warm, ahead of the cold fronts. Multi celled storms are usually the most common storm that you see, but it isn't the worst storm you can…

ever seen a powerful wind storm that destroyed houses, uprooted, and totaled cars? What are these mysterious, naturally occurring wind storms? Nobody truly knows how long these mysterious wind storms have been around. They do know this; that they are naturally occurring. These mysterious wind storms are called tornadoes. Tornadoes are very destructive and can cause people to be homeless. What are tornadoes? A tornado is a mobile, destructive vortex of violently rotating winds having the…

Objectives With the use of similar apparatus equipment through constant temperature at atmospheric pressure, the viscosity will be determined by tests in two different fluids in sets of two ball trials; along with data collected from a third set. By reducing errors and obstructions it will justify data for better discuss and calculated results, supporting the theory beyond the lab report to resonate in helping others comprehend the experiment. Procedure The experiment was…

Shear-induced particle migration in noncolloidal suspensions: Review article Daniel Galvez-Moreno a) Missouri University of Science and Technology, 219 Butler-Carlton Hall, 1401 N. Pine St., Rolla, MO 65409, USA. Synopsis INTRODUCTION Noncolloidal suspensions are composed by a liquid and a solid phase, which the latter is constituted by particles where Brownian motion, repulsion/attraction forces and Van Der Waals bonds are often negligible [1]. Nowadays, the success of many industrial…

rather a tensile force between the plate and the anchor device point. Multiple devices for anchoring have been developed over the years in an attempt to lower the costs and increase the amount of force the bolt is able to withstand, both tensile and shear. Grout can even be forced into the remaining gaps around the bolt after the anchoring device has been applied (Villaescusa, Windsor, & Thompson, 1999). Some of the types of resin bolts include; the paddle bolt, posimix, solid deformed, wiggle…

The idea of this investigation came from curiosity that I had ever since I was younger. I questioned why honey had a slower flow than water. This is a liquid’s resistance to flow and that is otherwise known as viscosity. This a concept that people would call thickness of a liquid. It makes sense that the thicker the liquid the viscosity would be greater. Viscosity describes the friction of a moving liquid. A liquid with high viscosity resists motion due to the fact its molecular composition…

Overview A hurricane is a tropical cyclone with damaging winds that can reach to 74 mph or higher. They occur in areas such as, the Atlantic Ocean, the Caribbean, the Gulf of Mexico, and the Central Pacific Ocean. In the western North Pacific hurricanes are known as typhoons, and likewise storms of similar effect in the Indian Ocean and North Pacific are known as cyclones. The name hurricane originated from the Caribbean god of evil, Huracan. Occurring 40 to 50 times a year globally, hurricanes…

develops below a heavy cumulonimbus cloud mass and extends toward the earth. The funnel twists about, rises and falls, and where it reaches the earth causes great destruction. The diameter of a tornado varies from a few feet to a mile; the rotating winds may attain velocities of 200 to 300 mi (320–480 km) per hr, and the updraft at the center may reach 200 mi per hr. The Enhanced Fujita scale is the standard scale for rating the severity of a tornado as measured by the damage it causes. A…
