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 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 […]
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 […]
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 […]
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 are the types of encoder?
What are the types of encoder? An encoder is classified into four types: mechanical, optical, magnetic, and electromagnetic induction types. There are four types of information necessary to rotate the motor with high accuracy: rotation amount, rotational speed, rotational direction, and rotational position. What are the two main types of encoders? There are two different […]
What are the different classes of UAS?
What are the different classes of UAS? Fixed wing and multirotor are the two main types of UAS. Each type has its own unique characteristics and uses, advantages and disadvantages. A Fixed wing UAV looks like an airplane. How does the FAA classify UAS? A UAS is an “aircraft” as defined in the FAA’s authorizing […]
