PPT-Temperature, Pressure, and Density

Danielle Hettmann and Chris Saleh SYST460 Fall 2011 Static temperature measure of the temperature at the surface of the aircraft Ambient temperature measure of the temperature of the air in the region surrounding the aircraft. Meters at Combined Temperature & Pressure. Calibration. Stand Update. Tony Wright. Customer Services Manager. Agenda. Background. Project requirements. Calibration Process. Current status. Test plan. What . is an advantage of composites that aids in lowering maintenance costs?. What is a potential disadvantage of composites in a hot climate or conditions?. Describe the care maintainers must utilize with paint strippers on composite materials?. What is the axis of flight that runs from the nose tip to the tail of the aircraft?. Describes what happens to an aircraft when the CG moves rearward.. When flaps are extended during takeoff, what do they provide to the aircraft?. What is “pressure”, what is “density”, and how do we measure them?. Who contributed to our current ideas and theories about pressure?. Where can we see pressure measured on a daily basis?. Important Questions. 2. The denser the atmosphere…. the greater its weight, and . the greater its air pressure.. 3. atmospheric pressure -. . a.k.a. .; . barometric pressure or air pressure.. the pressure due to the weight of the overlying atmosphere..

Macroscopic vs. Microscopic Quantities. We have been studying the motion of regular-sized (. macroscopic. ) objects. We know these objects are made up of countless atoms and molecules (. Which one of these weighs more???. A kg of bricks or a kg of feathers?. Both of the objects are 1 kg… so they both weight the same. . So why do we want to say bricks????. A kg of bricks may not weigh more, but it does have a higher density!!!. Section 11.2 – Properties of the Atmosphere 8 th Grade Earth and Space Science Class Notes Temperature Temperature – measure of the average kinetic energy of the particles in a material Higher the temperature = faster particle movement Properties of the Atmosphere Heat vs. Temperature Temperature – measure of how rapidly or slowly molecules move around. Higher the temperature = faster particle movement Heat - is the transfer of energy that occurs because of a difference in temperature between substances Ch. 1.1pgs . 16-20. Book K . – .

Water is a heavy substance. Pure water weighs 62.4 . lb. (pounds) per cubic feet at . 4°C. . This . is a direct result of density. Since, density changes with differences in temperature, compression, substances in solution and substances in suspension; the weight of a cubic foot of natural water is not always the same. . 3. Its structure, composition and dynamics. In last week’s lecture, we focussed on how weather is generated.. The key ingredients are energy and gradients.. Last Week’s Lecture. Incoming energy from the Sun is balanced with outgoing radiative cooling of the Earth, resulting in an equilibrium temperature of about 15 °C. .
