Lecture Outlines 2000 Ian A. Waitz THERMODYNAMICS: COURSE INTRODUCTION Course Learning Objectives: To be able to use the First Law of Thermodynamics to estimate the potential for thermomechanical energy conversion in aerospace power and propulsion systems. Measurable outcomes (assessment method): 1) To be able to state the First Law and to define heat‚ work‚ thermal efficiency and the difference between various forms of energy. (quiz‚ self-assessment‚ PRS) 2) To be able to identify

consists of a closed cylindrical container housing the horizontal plate/hemispherical shell to receive the impact of the jet. The vertical water jet is produced by a pump forcing water through a nozzle of diameter 6mm for the flat plate and of diameter 8mm for the hemispherical set up. The flow rate through the nozzle is measured by a rotameter. The velocity of jet could be obtained by knowing the flow rate. 4 Experimental Procedure Switch on the motor and using the two gate valves control the flow rate

STEALTH TECHNOLOGY ABSTRACT: Stealth technology also known as LOT (Low Observability Technology) is a sub-discipline of military electronic countermeasures which covers a range of techniques used with aircraft‚ ships and missiles‚ in order to make them less visible (ideally invisible) to radar‚ infrared and other detection methods. The concept of stealth is not new: being able to operate without giving the enemy knowledge has always been a goal of military technology and techniques. However‚ as the potency

Chapter 6 Momentum Analysis of Flow Systems Chapter 6 MOMENTUM ANALYSIS OF FLOW SYSTEMS Newton’s Laws and Conservation of Momentum 6-1C Newton’s first law states that “a body at rest remains at rest‚ and a body in motion remains in motion at the same velocity in a straight path when the net force acting on it is zero.” Therefore‚ a body tends to preserve its state or inertia. Newton’s second law states that “the acceleration of a body is proportional to the net force acting on it and is inversely

Space-based solar power (SBSP) is the concept of collecting solar power in space for use on Earth. It has been in research since the early 1970s. SSPS consists of a space-based power generation/transmission facility that gathers sunlight‚ converts it into microwaves or laser beams‚ and transmits those to the ground; and a power receiving facility on the ground. Space-based solar power essentially consists of three elements: • a means of collecting solar power in space‚ for example via solar cells

exerted like a simple nozzle when the fluid accelerated due to the changes in the cross sectional area. The kinetic energy of the fluid increases and since energy is conserved‚ the pressure of the fluid drops. This is meant that the pressure behind the fluid forces it through the nozzle causing it to speed up. The accelerated fluid in the direction of acceleration is required by force. Every force has an equal and opposite reaction so an equal and opposite force is exerted on the nozzle. There are three

said it was‚ a prediction. This prediction can be reduced by spending a portion of that money to research more energy and cost efficient propulsion engines and fuel. Such propulsion engines are‚ conveniently‚ already in development‚ reducing the cost by subtracting the cost of the amount of research already done. This advanced propulsion engine is a plasma-propulsion engine which will get humans to Mars in only 40 days reducing the amount of time that they are exposed to

Technologies impact on the voyage of Christopher Columbus Christopher Columbus sailed the ocean blue in 1492. He did so using primitive technology compared to today’s standards. He had lunar maps‚ a compass‚ while navigators nowadays have GPS‚ superior building materials and techniques‚ and satellite communications. Christopher Columbus could have made great use of these technologies in his voyage to America. He used celestial navigation to get an idea of where he was going. With technology nowadays

Werner von Braun Von Braun’s life Born 23rd March 1912 in Germany (now Poland) Prosperous aristocratic family Early interest in astronomy fostered by being given a telescope Didn’t do well at school until he acquired a copy of “The Rocket into Interplanetary Space”‚ by Hermann Oberth‚ which inspired him to apply himself in maths and physics. 1932‚ graduated from Berlin institute of technology with a degree in mechanical engineering. Enrolled in University of Berlin. 1932

COOLING TOWER INTRODUCTION: Cooling towers are a very important part of many chemical plants. The primary task of a cooling tower is to reject heat into the atmosphere. They represent a relatively inexpensive and dependable means of removing low-grade heat from cooling water. The make-up water source is used to replenish water lost to evaporation. Hot water from heat exchangers is sent to the cooling tower. The water exits the cooling tower and is sent back to the exchangers or to other units
