EXERCISE 1 1. Write the following as full (decimal) numbers in SI units: (a) 286.6 mm‚ (b)85 V (c) 760 mg‚ (d) 60.0 ps‚ (e) 22.5 fm‚ (f) 2.50 GV. 2. A typical adult human lung contains about 300 million tiny cavities called alveoli. Assume that the alveoli are spherical‚ and that the volume of a typical human lung is about 2 liters‚ estimate the average diameter of a single alveolus. 3. Two vectors have length and What are the maximum and minimum magnitudes of their vector sum? 4. is a vector

CBE 6333‚ R. Levicky 1 Potential Flow Part I. Theoretical Background. Potential Flow. Potential flow is frictionless‚ irrotational flow. Even though all real fluids are viscous to some degree‚ if the effects of viscosity are sufficiently small then the accompanying frictional effects may be negligible. Viscous effects become negligible‚ for example‚ for flows at high Reynolds number that are dominated by convective transport of momentum. Thus potential flow is often useful for analyzing external

Jennifer Ingrum 02/01/11 The Central Nervous System or (CNS) is located in the center portion of the body as its name implies. The (CNS) is made up of the brain and the spinal cord. Our brain is in control of many very important body functions and sensations like these for example: sleep‚ muscle movement‚ memory‚ sexual activity‚ emotions‚ hunger and thirst. Our spinal cord extends several types of nerve fibers from the brain acts like a switching and relay terminal for the peripheral nervous

Descriptive research does not fit neatly into the definition of either quantitative or qualitative research methodologies‚ but instead it can utilize elements of both‚ often within the same study. The term descriptive research refers to the type of research question‚ design‚ and data analysis that will be applied to a given topic. Descriptive statistics tell what is‚ while inferential statistics try to determine cause and effect. Three main purposes of research are to describe‚ explain‚ and validate

Chapter Objectives To show how to use the method of sections for determining the internal loadings in a member. To introduce the concepts of normal and shear stress. To analyse and design members subject to axial load and direct shear. To define normal and shear strain‚ and show how they can be determined for various types of problems.

Chapter 8 Flow in Pipes 8-76E Solution The flow rate through a piping system between a river and a storage tank is given. The power input to the pump is to be determined. Assumptions 1 The flow is steady and incompressible. 2 The entrance effects are negligible‚ and thus the flow is fully developed. 3 The flow is turbulent so that the tabulated value of the loss coefficients can be used (to be verified). 4 The elevation difference between the free surfaces of the tank and the river remains constant

George Washington Carver was a clever man with big dreams and the intention of pursuing them. He is known to many as “The Peanut Man” for his extensive work on peanuts. During his lifetime‚ Carver discovered over 300 uses of the peanut as well as sweet potatoes. What many do not realize is the difficulty Carver faced during his career. Many people‚ schools‚ and places he visited rejected him simply because of his race. Due to this racial prejudice‚ Carver had a very hard time getting his inventions

Prompt #2: How does point of view in “Cathedral” determine the plot? What it means to “see” another frequently depends on the maturity level of the viewer. This point is powerfully made by Raymond Carver in his short story “Cathedral” about a man who is navigating life “blind”‚ despite having normal vision. Carver tells his story using the husband’s point of view as the husband meets his wife’s long time friend‚ Robert‚ a man who ‚ despite being physically blind‚ sees life clearly. The point of view
