GAS DYNAMICS AND JET PROPULSION 1. What is the basic difference between compressible and incompressible fluid flow? Compressible 1. Fluid velocities are appreciable compared with the velocity of sound 2. Density is not constant 3. Compressibility factor is greater than one. 2. Write the steady flow energy equation for an adiabatic flow of air. In an adiabatic flow q = 0. Therefore energy equation becomes. 2 c12 c2 h1 + + gZ1 = h2 + + gZ 2 + Ws 2 2 Incompressible 1. Fluid velocities are small

current to "shock" the heart in order to restart a rhythm and beat. It should be used when a person goes into sudden cardiac arrest. AED stands for automated external defibrillator. The steps for using an AED are 1. turn on AED. 2. expose victims chest and wipe dry to ensure that the pads stick properly to the chest. 3. Apply the pads to chest. 4. plug the connector into AED‚ if necessary. 5. Let the AED analyze the heartbeat‚ and tell all bystanders to stand clear. 6. If the AED says a shock is needed

Why are floating rates considered to be superior to fixed rates in dealing with major shocks such as oil price increases? Explain why floating exchange rates did not produce a reduction in the US balance of payments deficit during the early 1980s? Describe the system that was developed to replace floating exchange rates. First we need to explain what fixed and floating exchange rates are. Fixed exchange rate regime is a regime in which central banks buy and sell their own currencies to keep

In 1963‚ a Phycologist at Yale University‚ known as Stanley Milgram‚ provided one of the most famous studies of obedience in psychology. He conducted an experimentation concentrating on the dispute amongst a response to a direct order from a superior and the internal logic of what is right or wrong in one’s behaviors or motives‚ compelling towards right action. The principal objective was to see how far a human would go when an authority ordered them to kill an innocent individual. Milgram wanted

In other words‚ people think that they would say no to an authority figure who ordered them to shock a person. In the new study‚ the researchers noted that the Milgram experiments had never been conducted in central European countries‚ which were once a part of the Soviet Union. The leaders of the region placed people there under communist rule and

Oil price fluctuations have affected the people and economies of the U.S. for most of the twentieth century. The commodity has seen minor changes and major fluctuations during this period. Major price changes within a short timeframe are called shocks. The research I propose will attempt to answer the question: What is the impact of changing oil prices on the macro economy of a country? Research has demonstrated oil price fluctuations do impact economies as well as supply of and demand for the

of receiving electric shocks would lead to stress-related illness in monkeys‚ and whether this would interact with the degree of control over the shocks. Procedures: Monkeys received electric shocks to their feet at 20 second intervals for periods of six hours at a time‚ with six hours` rest in between The electric foot shocks were not signalled Monkeys were run in pairs‚ with one in each pair - the so called "executive monkey" - able to press a lever to postpone shocks for 20 seconds The other

this test‚ he gathered random people and assigned them as the “teacher”‚ and placed them in a room with the controls for a shock machine (with various settings‚ from slight shock to XXX). Then he placed a confederate in a room‚ attached to a shock machine‚ who was the “student”. The “teacher” was to ask them questions and for every they got wrong‚ the “teacher” had to shock them‚ however the “student” was simply just pretending to get shocked. As the experiment continued‚ the “student” would begin
