Running Head: STORM CHASERS Storm Chasers Gurpreet Singh 200298384 History Firstly the storm chasing is started by David Haodley. He also invents a magazine called storm track magazine and the main motive of that magazine is to bring chasers community together. After that Neil ward was the scientific chaser. He used to chase the storm in a scientific manner. He made many new ideas about the forecasting of upcoming storms. Early Measurements and Observations After the Thunderstorm

How Tornadoes form Do you know what an F5 tornado is?This is one of the facts you will learn in this paper. This paper will discuss what causes tornadoes, the damage they cause, and the different types of tornado. The first topic is the different types of tornadoes.One type of tornados is a waterspout it is a column of rotating water.A cumulus cloud must be present for a tornado to form.Also cold air overlapping warm air has to happen.They can have winds up to 200mph and

definition of a fluid? A substance that deforms continuously when acted on by a shearing stress of any magnitude. 2. Normal force per unit area in a fluid is called what? Pressure 3. True or False: - Static fluids are not subjected to shear force at any time. T 4. True or False: - Normal forces can occur in a fluid whether it is static or Moving T 5. What is the relation between absolute pressure and gage pressure? Absolute pressure can be found from the gage pressure

stream is disturbed, its inertia will tend to move it in a new direction, however the viscous forces from the surrounding fluid will tend to move it in the general direction of flow. If the shear forces are large enough to overcome any deviation, then we have viscous or laminar flow. However, if the shear forces are relatively weaker, and not sufficient to overcome the inertia of the particles, then we have turbulent flow. [pic] Therefore it is the ratio of the inertia to the viscous forces

Summary/ Abstract Thin-walled pressure vessel provides an important application of the analysis of plane stress. Since their walls offer litter resistance to bending, it may be assumed that the internal forces exerted on a given portion of wall are tangent to the surface of the vessel. The resulting stresses on an element of the wall will thus be contained in a plane tangent to the surface of the vessel. In this experiment, we are going to determine the circumferential stress under open condition
