pH and Chromatography Lab Report Kevin Rivera Biology Mr. Langley 2C 10/7/13 Introduction In this lab‚ of pH and Chromatography‚ in the pH aspect of the lab we are trying to figure out the pH level of certain chemicals by writing down of known solutions to find the type of unkown solution using pH standards. In the Chromatography‚ we are trying to separate the chemicals using water and a piece of paper. Methodology Materials: Safety Goggles pH indicator & pH indicator key

ENT 310 Fluid Mechanics Midterm #1 – Open Book and Notes Name _______________________ 1. (5 pts) The maximum pressure that can be developed for a certain fluid power cylinder is 50.0 MPa. Compute the force it can exert if its piston diameter is 100 mm. 2. (5 pts) Calculate the weight (in Newtons) of 100 liters of fuel oil if it has a mass of 900 Kg. 3. (5 pts) The fuel tank of a truck holds 0.20 cubic meters. If it is full of gasoline having a specific gravity of 0.68‚ calculate the weight

I. Lubricants selection and Application A.Viscosity Most important property of any lubricant is viscosity. A common mistake when selecting a grease is to confuse the grease consistency with the base oil viscosity. Because the majority of grease-lubricated applications are element bearings‚ one should consider viscosity selection for those applications. While most would not use an EP 220 gear oil for an oil-lubricated electric motor bearing‚ many people will use a grease containing that same oil

Company Case 11.1: New Balance “Experiences” China August 26‚ 2011 New Balance has been in business for 103 years. The company started in Boston manufacturing shoes of police officers‚ waiters and any other occupations that kept people on their feet all day. In the 1970’s New Balance switched its focus and decided to make athletic shoes for all athletes. New Balance marketing department decided it was time to go overseas and to make money so‚ they open retail store in 2010. The stores are

1. Using diagrams and/or graphs‚ explain the following terms: a. Pressure Head pressure head [′presh·ər ‚hed] (fluid mechanics) Also known as head. The height of a column of fluid necessary to develop a specific pressure. The pressure of water at a given point in a pipe arising from the pressure in it. b. Total Discharge Head Total discharge head refers to the actual physical difference in height between the liquid level in the pit and the highest point of the discharge pipe or water level in

Q: Analyse the impact of changes in the global economy on Australia’s Balance of Payments. The Balance of Payments is a record of all of Australia’s transactions with the rest of the world in one year. There are three main components; the current account (CA) and the capital and financial account (KAFA). The current account concerns the balance of goods and services‚ net primary and net secondary income. The capital and financial account consists of foreign aid‚ intellectual property‚ investment

Case Study: Newsflash! Transport Proteins on Strike! 1. What is the meaning behind the PHOSPHOLIPIDS’ chant? Phospholipids make up most of the cell membrane‚ in a phospholipid bilayer. Phospholipid molecules form two layers‚ with the hydrophilic (water loving) head facing the extracellular fluid and the cytosol (intracellular) fluid‚ and the hydrophobic (not water loving) tails facing one another. The cell membrane is constructed in such a way that it is semipermeable‚ and allows oxygen

This way of balancing the powers was called checks and balances. The legislative branch can check the executive branch by: refusing to pass a bill the president wants‚ passing a law over the president’s veto‚ using the impeachment powers to remove the president from office‚ refusing to approve a presidential

CBE 6333‚ R. Levicky 1 Potential Flow Part I. Theoretical Background. Potential Flow. Potential flow is frictionless‚ irrotational flow. Even though all real fluids are viscous to some degree‚ if the effects of viscosity are sufficiently small then the accompanying frictional effects may be negligible. Viscous effects become negligible‚ for example‚ for flows at high Reynolds number that are dominated by convective transport of momentum. Thus potential flow is often useful for analyzing external
