As the assistant to Michael Brune‚ the executive director of the Sierra Club‚ I am in full support of The Exploratory Fracking and Extraction act. I would like to express concerns associated with hydraulic fracturing‚ or fracking‚ on behalf of the Sierra Club. Critical problems that are commonly brought to attention are: contamination of water supplies‚ seismic activity caused by fracking‚ and it worsens the current condition of the climate. Fracking wells inject water‚ sand‚ and chemicals deep

Midterm Exam II Solution‚ ME 342 Fluid Mechanics (Spring 2013) 1. Consider a steady‚ incompressible‚ y=+h b viscous flow of viscosity due to y a pressure gradient x inside a channel of two fixed u=u(y) plates at a distance of 2h‚ as shown in the figure. Neglect a gravity effect. The channel width y=h b is W and it is very long compared to the channel length L (i.e.‚ W>>L) so that it is still valid to assume that the channel flow is a two-dimensional plane flow ( ) and an axial flow (v = w = 0)

microfuge tube. Place this tube directly into liquid N2 to freeze plant tissue. 2) Remove tubes from the liquid N2 and quickly grind the plant tissue with a pestle. Add 300 L of Methanol 1%HCl and continue to grind the plant tissue. Allow extraction to occur overnight in a dark refrigerator. 3) Add 200 L Milli-Q H20 to each tube. Next‚ go to the fume hood and add 500 L of chloroform to each tube. Spin the tubes in a centrifuge set at the highest rpm for 2-5 minutes. 4) Return to

There has been much debate in recent years among politicians‚ military officials‚ and civilians on whether or not the U.S. should be fully withdrawn from Afghanistan‚ regardless of the country’s economic and military capabilities. There has also been a proposed timetable‚ which President Obama says is in effect and currently being executed‚ to have up to ninety percent of our military personnel out of the country by no later than 2014. It is imperative that we extract our forces out of Afghanistan

OK 73019 Dr. Nollert‚ The experiment performed was Experiment IV: Fluid Flow Meters and Tray Hydraullics. The group was composed of Alex Long‚ Khanh Ho‚ Tricia Heitmann and myself. The first day of experimentation was April 16‚ 2013. On this day‚ Alex and I ran the sieve tray apparatus to study the vapor and liquid tray hydraulics parameters for sieve type crossflow distillation trays. Tricia and Khanh ran the fluid flow apparatus to determine the operating characteristics of the Venturi

Laboratory #16: Analysis of Grease in Water by Solvent Extraction Experiment Date: 2/19/10 Due Date: 2/26/10 II. Objective The goal of this lab was to determine the amount of impurity‚ in the form of oil‚ in water using the method of solvent extraction‚ also known as liquid-liquid extraction‚ a method of separating two materials with different physical and/or chemical properties. Two methods of evaporation will be used to finally determine the concentration of impurity- one using an explosion-proof
