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.
| |hot water plus match |Air inside bottle was very foggy with the presence of smoke. | (4 points) 1. Cloud formation is really just the process of water vapor turning to liquid in the air. Name that water cycle process and explain why it occurs in the air? Hydrologic Cycle The elements that combine to make water Hydrogen and oxygen are found in dust, grasses, and other stuff that formed Earth.
The Spacecraft controls the telescope, supplies power to the instruments and handles its data, and communicates with Earth. The Cryogenic Telescope must be simultaneously warm and cold to function. Everything must be cooled to only a few degrees above absolute zero, this is achieved with the onboard tank of liquid helium. Spitzer is the largest infrared telescope to be launched into space. Goals: The main goal of this mission was to gain a new kind of understanding about space by viewing it through infrared radiation.
For the elastic collision we had the gliders set up so they would bounce off each other when they collided. We tracked each glider from both sides of the track and used the velocity to calculate momentum, before and after. The inelastic collision had the same setup, but the gliders were now setup to stick together when they collided. This was done with Velcro strips that stuck together when they met. Data and Analysis The following table shows the values we got during the elastic collision Elastic Data | | Pred | Pblue | Δp | | 0.04 | -0.07 | 0.03 | | 0.01 | 0.07 | 0.08 | | 0.2 | -0.3 | 0.1 | Average | 0.09 | -0.09 | 0.06 | Our uncertainty is calculated using the general formula for multiplied/divided values giving us an error of 0.1 kg*m/s.
Hurricanes Hurricanes, also known as tropical cyclones, are low pressure storm systems that form on open water and feed on heat released when moist air rises. Hurricanes are recognized on radar by their distinct pin wheel shape. When hurricanes begin to take shape they are called a tropical storm. The word “tropical” is used because most of these storms are formed by the very warm water of the tropics. Hurricanes need the ocean’s water temperature to be about 80 degrees to a depth of about 150 feet.
What about at an increased temperature? Answer = The weather may be calm with decreased temperatures verses a warmer temperature. The sun heats the water to evaporate and to produce water vapors that transform into clouds. According to our lab manual, clouds form at many different altitudes in the troposphere when water vapor in warm air rises and cools. Experiment 1: Water Movement POST LAB QUESTIONS 1.
The planet moves whenever the two plates get tangled together. The energy that moves the plates become saved and whenever that energy is ultimately releases it triggers the planet earth in order to shake (Nelson, 2011). Earthquakes are measured with a seismometer, which is also known as a seismograph. A seismometer measure as well as notes the moves under the Planet’s surface which includes seismic waves triggered by earthquakes. A seismometer permits seismologists to produce a map of the Planet’s inner surface.
Try collisions in which the initial velocity of glider2 is not zero. You may need to practice a bit to coordinate the gliders so the collision takes place completely between the photogates. Data and Calculations For each time that you measured, calculate the corresponding glider velocity (e.g., v1, = L1/t1i). Use your measured values to calculate Eki and Ekf, the combined kinetic energy of the gliders before and after the collision. Record your results in the table.
Transpiration removes water from plants and soil. Air currents take water vapour into the atmosphere where cooler temperature causes it to condense into clouds. Air currents move water around the globe; cloud particles collide and fall out of the sky as snow, hail or sleet. Most water falls back into ocean or on land as rain where the water flows over ground as runoff. Some of runoff enters rivers flowing water towards ocean where water cycle had started.
