Determine Fa, the force applied to the glider by the hanging mass. (Fa = mag; g = 9.8 m/s2 = 980 cm/s2) Analysis Draw a graph showing average acceleration as a function of applied force,
FOR A MOMENT, THINK OF AN AIRPLANE MOVING FROM LEFT TO RIGHT AND THE FLOW OF AIR MOVING FROM RIGHT TO LEFT. THE WEIGHT OR FORCE DUE TO GRAVITY PULLS DOWN ON THE PLANE OPPOSING THE LIFT CREATED BY AIR FLOWING OVER THE WING. THRUST IS GENERATED BY THE PROPELLER AND OPPOSES DRAG CAUSED BY AIR RESISTANCE TO THE AIRPLANE. DURING TAKE OFF, THRUST MUST BE GREATER THAN DRAG AND LIFT MUST BE GREATER THAN WEIGHT SO THAT THE AIRPLANE CAN BECOME AIRBORNE. FOR LANDING THRUST MUST BE LESS THAN DRAG, AND LIFT MUST BE LESS THAN WEIGHT.
And limiting reagent which is the reactant that is completely consumed when a reaction is run to completion. III. Summary of Procedure In this lab the first procedure was to measure the initial temperature of NaOCl and of Na2S2O3 and measure it with a thermometer and then record it. The same thermometer is used for measuring both solutions, but the thermometer should be washed with distilled water after the using it in one solution. Afterwards a small amount of NaOCl was added to the graduated cylinder.
-We measured in each chemical and added water besides, HCl we added NaOH. Next, we measured the water temperature to begin with then added the substance to it to determine the finally temperature. We minus the initial and finally to decide if the reaction is exothermic and endothermic. 5. Describe the anticipated temperature change of a system in which an exothermic process is taking place.
Different compounds boil at different temperatures because each has a different, characteristic vapor pressure: compounds with higher vapor pressures will boil at lower temperatures. Boiling points are usually measured by recording the boiling point (or boiling range) on a thermometer while performing a distillation. This method is used whenever there is enough of the compound to perform a distillation. The distillation method of
Pre Lab Objective: The purpose of this lab is to obtain the mass and volume of two different metal samples, to graph data, to obtain the slope of graphed data and to display a best fit curve of experimental data in order to graphically determine the density of each metal Background: Understanding the relationship that exists between a substance’s mass and its volume. This relationship is expressed by the physical property called density. (D = M/V). In order to determine the volume of solids, a technique called water displacement is used. A fixed amount of water is added to a graduated cylinder and the volume of water is recorded.
Therefore the alkalinity of water samples is being calculated. In the second approach, the two volume readings for the respective amounts of sulfuric acid used are being determined an indicator based method. Congo red and bromocresol green are being used as the indicators. Procedure (Outline provided as pre-lab): A. The pH meter was calibrated using standard pH solutions provided.
Experiment 1: Pressure, Temperature, and Velocity Measurement Objective: The objective of this experiment is to determine the pressure and density of laboratory air, calibrate a pressure transducer and scannivalve, then determine the test section speed as a function of fan speed using three methods of velocity measurement. Equipment: Absolute pressure transducer, digital thermometer, pressure transducer (voltmeter), micromanometer, scannivalve, Pitot tube, low-speed wind tunnel. Part 1: Measurement of Atmospheric Pressure and Density 1. Read the barometer and wind-tunnel thermocouple. 2.
When the fuels combust, oxygen and fuels react, and heat released. The water then absorbed the heat from the combustion. In this experiment the calorimeter of energy is used to measure the temperature of the heat that is released from the cashew. The equation to find the energy produce during
This makes it possible to equate the expansion of the reservoir fluids upon pressure drop to the reservoir vodage caused by draw of oil, gas, and water minus the water influx. Successful application of this method requires an accurate history of the average pressure of the reservoir. As well as reliable oil –gas and water –production data and (PVT) data on the reservoir fluids, if sufficient pressure and production performance data are recorded and (PVT) data describing the reservoir fluid behavior is available. The amount of oil or gas in place in a reservoir sometimes may be the computed by material balance
