Program) EEE-112 Engineering Mechanics and Thermodynamics Assignment # 1 Submission date: Mon‚ Sep 17‚ 2012 1. A certain fluid at 10 bar is contained in a cylinder behind a piston‚ the initial volume being 0.05 m3. Calculate the work done by the fluid when it expands reversibly: a. at constant pressure to a final volume of 0.2 m3; b. according to a linear law to a final volume of 0.2 m3 and a final pressure of 2 bar; c. according to a law Pv = constant to a final volume of

Experiment 3: Solution Calorimetry: Thermodynamics of Potassium Nitrate II. Abstract A determination of thermodynamic variables of KNO3 is presented. KNO3 was heated and dissolved in varying volumes of distilled water. Upon dissolution‚ the KNO3 solution was removed from heat and the temperature was recorded once crystals formed. For each solution‚ ∆G the Ksp were found with the temperature and molarity values. ∆H and ∆S were found through the linearization of the data with

Thermodynamics of a laptop computer Electronic computers currently have many orders of magnitude more thermodynamic process of freedom than information-bearing ones (bits).Because of this‚ these levels of description are usually considered separately as hardware and software‚ but as devices approach fundamental physical limits these will become comparable and must be understood together. Using some simple test problems‚ I explore the connection between the information in a laptop computer and

The First Amendment In my opinion freedom of speech and First Amendment rights are crucial to higher education because For One‚ Freedom of speech is the right for an individual to speak their mind without interfering with the law and the First Amendment is the law respecting an establishment of religion ‚ the right to free expression‚ infringing on the freedom of the press‚ and freedom of belief. Which all ties into education itself sine the majority of it is sourly based on communication.

begging‚ and sexual exploitation. Child labor is tolerated in communities where the prevailing public view downplays the dangers of children working or where it has become part of culture‚ tradition or family expectations. Poor enforcement of labor laws‚ corruption and weak protection are all factors contributing to child labor. Child labor is attractive to employers motivated by profit because children are easier to control‚ exploit and they are more compliant. Children are less likely to demand

9. A concrete highway is built of slabs 14 m long (20Cº). How wide should the expansion cracks be (at 20Cº) between the slabs to prevent buckling if the temperature range is -30Cº to +50Cº? I know I use the formula: L = LoT L = ? (Change in length of the slabs. We are solving for this.) = 12e-6 (Coefficient of expansion. I looked it up on page 388.) Lo = 14 m (Initial length of slabs.) T = 30 Cº (50Cº - 20Cº) (Change in temperaure. You only care about the hottest number

7 days. And I was right! ATW was similar to Basic Research‚ but then‚ it is on an “average round”‚ as what some students say. This elective came in technicality and in advance because it has strict observance of rules and standards. And now‚ as the 1st quarter ends‚ I can fully scent the start of our journey as writers or authors of tomorrow. Letters‚ letters‚ letters… Every day we discuss about the lessons of using a sheet of paper and a pen to make a letter. Now‚ let me be factual. There are

EXERCISES on Application of Newton 2nd Law-(1st PART) 56. Two boats pull a 75.0-kg water skier‚ as illustrated in Fig. 4.32. (a) If each boat pulls with a force of 600 N and the skier travels at a constant velocity‚ what is the magnitude of the retarding force between the water and the skis? (b) Assuming that the retarding force remains constant‚ if each boat pulls with a force of 700 N‚ what is the magnitude of the acceleration of the skier? Figure 4.32 Double tow. See Exercise 56. 57.
