What is the purpose of the Reynolds Transport Theorem? Reynolds transport theorem (RTT) expresses the relationship between the rate of change of extensive property of a system and for the control volume. The main purpose of the RTT is to provide the link between the system and control volume. What is the relationship between the […]
What category does mechanic fall under?
What category does mechanic fall under? Most mechanics specialize in a particular field, such as auto body mechanics, air conditioning and refrigeration mechanics, auto mechanics, bicycle mechanics, boiler mechanics, general mechanics, industrial maintenance mechanics (millwrights), motorcycle mechanics, aircraft mechanics, heavy duty equipment mechanics. Can I sue a backyard mechanic? Yes. However, the way to sue […]
What does a negative reading on a voltmeter mean?
What does a negative reading on a voltmeter mean? If they are switched, there will be a negative voltage. If the poles of your voltmeter are correctly connected, there is a possibility that the battery suffered a phenomenon called “polarity reversal”. This is a rare phenomenon that can happen at the end of a discharge […]
How does a shell and tube heat exchanger work?
What are the movements of an airplane?
What are the movements of an airplane? There are three types of movement of an aircraft: pitch, yaw, and roll. Roll is controlled by the ailerons and rotates the airplane. Yaw turns the airplane and is controlled by the rudder. Finally, pitch is controlled by the elevator and changes the altitude of the airplane. What […]
What is hydrodynamic and thermal boundary layer?
What is hydrodynamic and thermal boundary layer? This thin layer of changing velocity has been called the hydrodynamic boundary layer; a concept first suggested by Ludwig Prandtl in the year 1904. Heat transfer occurs due to heat conduction and energy transport by moving fluid within this thin layer. What is the difference between hydrodynamic and […]
What happens if you apply greater force to an object?
What happens if you apply greater force to an object? The greater the force that is applied to an object of a given mass, the more the object will accelerate. For example, doubling the force on the object doubles its acceleration. Does greater speed mean greater force? Then what do forces do to an object? […]
How do I create a Monte Carlo simulation in Excel?
How do I create a Monte Carlo simulation in Excel? To run a Monte Carlo simulation, click the “Play” button next to the spreadsheet. (In Excel, use the “Run Simulation” button on the Monte Carlo toolbar). The RiskAMP Add-in includes a number of functions to analyze the results of a Monte Carlo simulation. How do […]
Why incremental development is the most effective approach for developing business software systems?
Why incremental development is the most effective approach for developing business software systems? Business software systems usually complex, software intensive, and frequently being changes when business goals or processes are changed. So incremental development is better. Real-time systems usually involve many hardware components which are not easy to change and cannot be incremental. Why do […]
Why does a mixed or unmixed fluid arrangement influence heat exchanger performance?
Why does a mixed or unmixed fluid arrangement influence heat exchanger performance? If you’re asking about the effect of mixing or not mixing a fluid as the fluid is passing through the heat exchanger, I believe that the reason mixing provides better performance is because a mixed fluid will transfer thermal energy, or really just […]
