What can you do with a vacuum former? Vacuum forming is a manufacturing process by which a sheet of plastic is heated and pressed over a form to create a part. This process is used to create many of the products in your home such as plastic containers, tubs, sink units, and electrical enclosures. How […]
What is the relative humidity at dew point temperature?
What is the relative humidity at dew point temperature? The dew point is the temperature the air needs to be cooled to (at constant pressure) in order to achieve a relative humidity (RH) of 100%. At this point the air cannot hold more water in the gas form. What is meant by dew point temperature? […]
What did Percy Spencer died of?
What did Percy Spencer died of? Septe What was the microwave originally invented for? Percy Spencer How old was Percy Spencer when he invented microwave? 18 months old What was Percy Spencer’s job? Inventor What type of engineer was Percy Spencer? electrical engineers When did Percy Spencer die? How old is Percy Spencer? 76 years (1894–1970) […]
What is the physical property of ductility?
What is the physical property of ductility? Ductility is the physical property of a material associated with the ability to be hammered thin or stretched into wire without breaking. A ductile substance can be drawn into a wire. Is brittleness a physical property? Brittleness is a characteristic that describes chalk. Any such characteristic of a […]
Is air pressure higher above an airfoil?
Is air pressure higher above an airfoil? The shape of an airfoil causes air to flow faster on top than on bottom. The fast flowing air decreases the surrounding air pressure. Because the air pressure is greater below the airfoil than above, a resulting lift force is created. Why does the air flow faster over […]
What are properties that describe chemical reactions?
What are properties that describe chemical reactions? The change of one type of matter into another type (or the inability to change) is a chemical property. Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion. Why any chemical reaction is a chemical property? A chemical property is any of […]
How do you calculate ZL?
How do you calculate ZL? Line impedance is the ratio of complex line voltage to complex line current. You can calculate it with the following equation: Z(z) = V(z)/I(z). How do you find the input impedance of a transmission line? The input impedance of a terminated lossless transmission line is periodic in the length of […]
What does a project engineer?
What does a project engineer? A Project Engineer manages technical or engineering projects. Project engineering is typically the management of engineering and technical projects – this includes management of personnel, budget, and scheduling to deliver a successful project outcome that is fit for purpose. What are the duties and responsibilities of site engineer? Civil Site […]
What is Fibonacci series in programming?
What is the maximum efficiency of a heat engine?
What is the maximum efficiency of a heat engine? is the total heat energy input from the hot source. Heat engines often operate at around 30% to 50% efficiency, due to practical limitations. It is impossible for heat engines to achieve 100% thermal efficiency () according to the Second law of thermodynamics. Is a temperature […]
