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

The human body is a remarkable species‚ capable of doing some of the most amazing things known to man. It requires a lot of energy and the organisms that make it up constantly have a task to perform. One of the most important functions in the human body is called cellular respiration. It is defined as a process in which cells take the food humans ingest and turn it into energy that can be used by the body in the form of ATP‚ also known as‚ adenosine triphosphate. The creation and distribution of

I. Introduction What are Steroids? Corticosteroid drugs‚ called "steroids" for short‚ are potent chemical substances which can reduce swelling and inflammation quickly. These drugs are closely related to cortisol‚ a hormone produced on the cortex of the adrenal glands. Corticosteroids are used in arthritis treatment because of their anti-inflammatory properties‚ but recommended as a low-dose or short-term treatment when possible to minimize side effects. Corticosteroids are not the same as "anabolic

Fluid Report 2 In the derivation of Bernoulli’s equation‚ the assumption of the inviscid and incompressible flow is used. However in the real case‚ the viscosity cannot be neglect and the density of the flow is not always constant. Thus Bernoulli’s equation is not always correct. For the lab‚ it is reasonable to assume the flow is inviscid and incompressible. Firstly‚ the pitot was placed at the center of the flow. The skin friction (effect of viscosity) is inversely proportional to distance

Fluid intelligence reflects information processing capabilities‚ reasoning‚ and memory. It is used to evolve the ability to think clearly. For instance‚ a person who is asked to arrange a series of letters according to some rule or to memorize a set of numbers uses fluid intelligence. Although it is defined as the inmate and learning caoacity of all individuals. To my knowledge fluid intelligence is used in so many ways‚ throughout the country. It normally affect’s children during childhood and

World there are several things are abnormal and are frowned upon here on Earth‚ while these things are abnormal here in the novel these things are completely normal and that is just the way that things are done. One such example is shocking babies to train them‚ while on Earth this idea is taboo and highly frowned upon in the novel this is normal and the way that babies learn about how to do things. A second thing that is strange in A Brave New World would be the sexaphones‚ a musical instrument that

Throughout the play‚ “The Normal Heart” Kramer address more than just the AIDS epidemic; he teaches the audience to take pride and rejoice with one another being gay rather than hiding it to “protect” their social appearance. Within his efforts‚ Kramer uses relatable characters and communities to further his ideas. More importantly‚ Kramer never strays from writing the actual truth‚ including these ideas: the New York Times suppressing the gay community‚ Mayor Koch rejecting furthering the studies

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 the outlet. c.
