Record the readings of the three instruments at eight different speed settings of the tunnel: 15, 20, 25, 30, 35, 40, 45, & 50. 4. Plot two calibration curves with pressure transducer reading as the abscissa and micromanometer reading as the ordinate for the first, and micromanometer versus scannivalve as the second. Convert micromanometer data to read as total pressure in SI units [Pa]. 5.
Continuity Tester - is an item of electrical test equipment used to determine if an electrical path can be established between two points; that is if an electrical circuit can be made. 13. Category 5e/6 Cable - is a twisted pair cable for carrying signals/ is a standardized cable for Gigabit Ethernet and other network physical layers that is backward compatible with the
Physics 1408 Section E1 Standing Waves in a Vibrating Wire Callie K Partner: Miguel E Date Performed: March 20, 2012 TA: Raziyeh Y Abstract This lab had two purposes. The first was to determine the relationship between the length of a stretched wire and the frequencies at which resonance occurs. The second was to study the relationship between the frequency of vibration and the tension and linear mass density of the wire. In the first part we found the resonance, frequency and wavelength of a wire and used this data to calculate the speed of the traveling waves. For first harmonic, our wavelength was 1.200 m, found by the formula λ=2L/n.
NT1310 Unit 6 Assignment 1: Cable Tester The three cable testers I would choose would be the optical loss test set and test kit, the Time-Domain Reflectometers (TDR), and the tone generators. The Optical Loss Test Sets and Test Kits is a useful tool in a lab or for testing patch cables, two separate devices would be needed to test a permanently installed link because you have to connect the light source to one end of the cable and the power meter to the other. You need both an optical power meter and a light source in order to properly install and troubleshoot a fiber-optic network, and you can usually save a good deal of money and effort by purchasing the two together. You will thus be sure to purchase units that both support the wavelengths and power levels you need and that are calibrated for use together. You can purchase the devices together as a single combination unit called an optical loss test set (OLTS) or as separate units in a fiber-optic test kit.
To measure the circumference of the disk, make a mark on the disk and place the disk on the meter stick with the mark coinciding with a meter stick reading. Roll the disk for one revolution along the meter stick to obtain the circumference. Measure and record this value. Do this for each disk. Iv .
PK-S Lab 03 – Lab Report Name: ____________________ Section: ___________________ EXPERIMENT 3: Trigonometric Measurements Procedures: 1. Experimental measurement of the angles and sides of a right triangle: A. Create a triangle by taping a string against a wall and taping the bottom of the string to the floor or a table set against the wall. Make sure that the wall is perpendicular to the floor or table by measuring angle C, which should be 90o. B.
In the other, aluminum leftovers, the activity series was used to understand how and why the reaction took place and stoichiometry was used to predict the amount of aluminum that should have reacted in the following equation: 3CuCl2 * 2H2O (aq) + 2Al (s) 2AlCl3 (aq) + 3Cu (s) + 6H2O Stoichiometry’s importance in the laboratory is well defined in the results of the previously mentioned experiments. Materials:
Next we will chart the data and form two different plots. The first plot will be actual temperature as a function of time. The second chart will be excess temperature as a function of time. On the second chart I will place an exponential trendline showing the equation of the line. Using this equation I can determine the cooling time constant for the block of steel.
Determination of Unknown Block Material and Uncertainty Analysis Xuan Wang TA: Saurabh Chawdhary ME4031W Lab Section 014 4:40PM Wednesday 2/10/2013 Abstract People discovered many methods to determine the properties of unknown materials (harness, density, or elastic modulus etc.). In this lab, the task is to find the density of an unknown block. If the dimensions and mass of unknown block can be obtained, the density can be calculated by block mass over block volume. After comparing the result density value to a reference chart, the specific material category can be determined. Dimensions can be measured by using a caliper and a micrometer and mass can be determined by putting the block onto an electronic balance.
The experiment was performed to evaluate the skills of an individual to perform some lab skills like filtration and decantation and use these skills to understand the concept of percent yield. The goal was to start with an initial mass of
