What happens to the viscosity of a Newtonian fluid? A Newtonian fluid is one whose viscosity is not affected by shear rate: all else being equal, flow speeds or shear rates do not change the viscosity. Air and water are both Newtonian fluids. Some liquids,c however, have viscosities that change with rate of shear. What […]

What is considered a scholarly journal? Definitions. Scholarly or peer-reviewed journal articles are written by scholars or professionals who are experts in their fields. In the sciences and social sciences, they often publish research results. Substantive news articles are reliable sources of information on events and issues of public concern. How do you know if […]

How does viscosity affect drag? Drag force arises when an object moves through a fluid or, equivalently, when fluid flows past an object. In general, the drag force grows larger with increased flow velocity, but viscosity is a complex phenomenon that cannot be reduced to the simple relationship “drag force is proportional to velocity”. What […]

How do you describe chemical engineering? Chemical engineering is the branch of engineering that deals with chemical production and the manufacture of products through chemical processes. This includes designing equipment, systems and processes for refining raw materials and for mixing, compounding and processing chemicals to make valuable products. What problems do chemical engineers solve? Chemical […]

What is the formula for curvature? The radius of curvature of a curve at a point M(x,y) is called the inverse of the curvature K of the curve at this point: R=1K. Hence for plane curves given by the explicit equation y=f(x), the radius of curvature at a point M(x,y) is given by the following […]

Which utility program reads an assembly language source file and produces an object file? Assembler What is object file in assembly language? An object file is a computer file containing object code, that is, machine code output of an assembler or compiler. The object code is usually relocatable, and not usually directly executable. There are […]

How do you put PCA on a dataset? To get the dataset used in the implementation, click here. Import the dataset and distributing the dataset into X and y components for data analysis. Doing the pre-processing part on training and testing set such as fitting the Standard scale. Applying the PCA function into training and […]

What is the principle of Pascal law? Pascal’s law says that pressure applied to an enclosed fluid will be transmitted without a change in magnitude to every point of the fluid and to the walls of the container. The pressure at any point in the fluid is equal in all directions. What is the definition […]

What happens if we reverse the polarity of the diode? If the polarity is reversed, they conduct current and there may not be any current-limiting resistance in the circuit to prevent them from overload. Now the diode conducts current, and because the current flow in a forward-biased diode increases exponentially with the voltage, it overloads […]

What is structural personal protective clothing designed to do? Figure 6.3 NFPA® 1971 regulates the clothing components that comply with the standard. Structural personal protective clothing is designed to cover all portions of your skin when you are reaching, bending, or moving. It is also designed to prevent heat transfer from the fire to your […]
