Explosivity of Magma 1. Factors Affecting Explosivity a. Gas Content – higher gas content have more explosive eruptions 2. Viscosity resistance to flow easy flowing magma (low viscosity) – gas bubbles dissipate – erupt effusively High Gas Content + High Viscosity = Explosive Volcanic Eruptions Viscosity Factors - Chemical Composition‚ the more SiO2 present‚ the higher the viscosity - temperature‚ the cooler‚ the more viscous The Higher the M Value

This could be improved by adding more methanol to the mixture before isolation. The mixture could also stay in the water bath for longer than 45 minutes to allow an adequate time for the tartaric salt to form. An extra 30ml of methanol was added to this experiment to get the tartaric salt to form and if more methanol was added‚ a higher percentage yield might have been obtained. The literature value for the melting point of

The Marsh funnel is a simple device for measuring viscosity by observing the time it takes a known volume of liquid to flow from a cone through a short tube. It is standardized for use by mud engineers to check the quality of drilling mud. Other cones with different geometries and orifice arrangements are called flow cones‚ but have the same operating principle. A modern plastic Marsh Funnel In use‚ the funnel is held vertically with the end of the tube closed by a finger. The liquid to be

Clay Loading and Dispersion Effects on the Rheological Properties of Unsaturated Polyester Nanocomposites Tony Nguyen (Mentor: Abbas A. Zaman‚ College of Engineering) ABSTRACT The objective of this work is to characterize the influence of clay loading and dispersion effects on the rheological properties of unsaturated polyester composites. Toughened unsaturated polyester (UPE) composites were synthesized by the blending of delaminated clay with unsaturated polyester. Rheological behavior is

FALL 2012 ME 305 FLUID MECHANICS I EXPERIMENT 1 MEASUREMENT OF FLUID PROPERTIES PREPARATION: In this course‚ you will conduct the experiments at the Fluid Mechanics Laboratory‚ by yourselves‚ without any help or instruction from the teaching assistants. You must read the lab sheet thoroughly and understand what you are expected to do (and why) for each experiment‚ before coming to the lab. At the end of each experiment‚ you will have to do certain calculations‚ present and plot (when asked)

This usually means the cell is dead. In this experiment‚ you will test the effect of three different alcohols (methanol‚ ethanol‚ and 1-propanol) on membranes. Ethanol is found in alcoholic beverages. Methanol‚ sometimes referred to as wood alcohol‚ can cause blindness and death. Propanol is fatal if consumed.

accurately weighed and transferred to the volumetric flask and was dissolved in 100 ml of methanol and made up to volume with same solvent. The solutions were filtered through a 0.45 μm nylon filter and sonicated for about 15 min and then volume made up with methanol. This solution was filtered to eliminate any insoluble matter. The filtrate was collected in a clean flask. Appropriate dilutions were made with methanol and measured solution (100 μg/ml) for both zero order at 275nm and first order derivative

Discussion In this experiment‚ the molar mass of two volatile liquids – methanol and an unknown liquid – were calculated for through the Dumas Method. Initially‚ the sets of Erlenmeyer flasks with aluminum foil and rubber bands were weighed. Next‚ volatile liquids were placed in 125mL Erlenmeyer flasks and covered with aluminum foil‚ but small holes were made into the foil. The flask was then heated in a water bath until all of the liquid evaporated. The flask was then removed‚ and weighed again
