...HYDRAULICS LAB #1 The objective of this lab is to test the fluid flow provided by the power unit at various discharge pressures, and create a power unit characteristic curve. 1. Build on the trainer the hydraulic circuit shown in the figure below, using the components listed here. hydraulic power unit (2) pressure gauges flow control valve (FCV) – simulated load flow-meter Page 1 of 2 2. Initial setup: a. Fully close (CW) the FCV, and fully open (CCW) the pressure relief valve on the power unit. b. Start the power unit, and slowly adjust the pressure relief valve until pressure gauge P1 reaches 50 bar. Let the unit run for a few minutes then check and adjust P1 if necessary. c. Do not touch the pressure relief valve for the remainder of the lab. d. Fully open the FCV. 3. Test: a. Record the pressures P1, P2 and the flow rate under the “Min.” column in the table below. b. Slowly turn the FCV CW, adding a simulated load to the system. When the pressure at P1 increases to 15 bar, stop and record pressure P2 and the flow rate. c. Repeat for all columns listed in the table. The final column, listed as “Max Pres.” should be run with the FCV fully closed. Note the sound of the power unit during this test. You should detect changes in tone as the load (pressure) is increased. P1 Pressure (bar) P2 (bar) Flow Rate (lpm) Min * 15 20 25 30 35 40 45 46 47 48 49 Max.

...Lab 1: Measurements What is the scientific method? This week we will start with a brief discussion of the scientific method in general. This will be followed by a more detailed description of how the scientific method will be applied in this course. In the end, this discussion will give you the format for the lab reports you will write over the next 15 weeks. Our first lab will focus on taking good measurements, graphing techniques, and how to extract the important information from the data to reach a conclusion. You will be measuring round objects, so you are invited to bring different-sized round objects to class on the first day. In preparation for class, consider how round objects can be measured. 1) Brainstorm to develop the testable question. How does one measure the roundness of a round object? 2) Develop the hypothesis. Note: While the relationship in this lab is very simple and should be well known, this will not always be the case. This lab is meant to introduce the lab format without too many complications. If the diameter is increased, then the circumference is increased in a directly linear proportional manner. 3) Brainstorm for variables: The two variables that make up the testable question must be included. Identify the variables. Independent: Diameter Dependent: Circumference Control: Round objects 4) Develop the design table. | |D(cm) ...

...Lab 1: Introduction Metric System Prefixes (to put in front of basic units): k = kilo = 1000 x c = centi = 1/100 of (which is 10-2 of) m = milli = 1/1000 of (which is 10-3 of) ( = micro = 1/1,000,000 of (which is 10-6 of) n = nano = 1/1,000,000,000 of (which is 10-9 of) (d = deci = 1/10 of ) [pic] (Note: The way to read the numbers above, for example, is: There are 1000 nm in one (m. There are 1000 (m in one mm.. etc.) To convert from one metric unit to a different metric unit (a different prefix): 1. First, decide how many places to move the decimal point (the number of 0’s in the chart above indicates the number of places to move the decimal point). 2. Next you need to decide whether to move the decimal point left or right. To decide this, think about which is the smaller unit. (The smaller the unit is, the more of them you need to get the same amount. e.g. pennies vs. dollars) NOTE: Here is another way to write the conversions, using distance (the meter is the basic unit for distance) as an example: 0.001 km = 1 m = 10 dm = 100 cm = 1000 mm = 1,000,000 (m = 1,000,000,000 nm The “staircase” method: One more way to remember about sliding decimal points when converting between prefixes in the metric system! [pic] Move the decimal point 3 places for every step you move on the “staircase”, and in the same direction traveled on the staircase (left vs. right). Unfortunately, you can see that the “c” prefix...

...Biology lab report: If you are taking a biology course, at some point you will have to do lab experiments. This means that you will also have to complete biology lab reports. The purpose of writing a lab report is to determine how well you performed your experiment, how much you understood what happened during the experimentation process, and how well you can convey that information in an organized fashion. Biology Lab Reports: Formats A good lab report has a format that includes five main sections. They are the introduction, methods and materials, results, discussion and conclusion, and citation. Keep in mind that individual instructors may have a specific format that they require you to follow. Please be sure to consult your teacher about the specifics of what to include in your lab report. Introduction: The introduction of a lab report states the purpose of your experiment. Your hypothesis should be included in the introduction, as well as a brief statement about how you intend to test your hypothesis. To be sure that you have a good understanding of your experiment, some educators suggest writing the introduction after you have completed the methods and materials, results, and conclusion sections of your lab report. Methods and Materials: This section of your lab report involves producing a written description of the materials used and the methods involved in performing your experiment. You should not just record a list of materials, but indicate...

...NUTRITION 121 HUMAN NUTRITION LABORATORY BACKGROUND AND METHODS MODULE #1 BODY COMPOSITION Late Labs: 10 point deduction! A report submitted >1 week late, will receive 0 points for the lab!! Written and edited by: Karon Felten and Nutrition 121 TA’s With Special Thanks to: Chris Pritsos Ph.D. Nutrition Department Chairman ABSTRACT: In nutrition, there are many factors that influence an individual’s health and body weight, such as heredity, food selection, eating behaviors, and physical activity. Scale weight is not always a good indicator of body fat, lean mass, body water or overall health (1). This laboratory experience will give students the opportunity to conduct physical assessments by evaluating body weight and body composition. To determine body weight and body composition, techniques such as bioelectrical impedance analysis (BIA), body mass index (BMI), waist circumference, wrist circumference for determining frame size, and a scale will be utilized. Students will also evaluate their own risk for cardiovascular disease and assess cardiovascular health in volunteers by measuring heart rate, filling out a heart disease risk score form, and estimating oxygen consumption and energy expenditure through a technique known as the Queens College Three-Minute Step Test. BACKGROUND: Your body is made up of the six essential nutrients: water, fat, protein, carbohydrates and various vitamins and minerals. Many factors can influence an individual’s...
