What is direct shear test for soil? From Wikipedia, the free encyclopedia. A direct shear test is a laboratory or field test used by geotechnical engineers to measure the shear strength properties of soil or rock material, or of discontinuities in soil or rock masses. How do you do a direct shear test? The testing […]

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 […]

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 […]

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 […]

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 many integers can be represented in 32 bits? The number 2,(or hexadecimal 7FFFFFFF16) is the maximum positive value for a 32-bit signed binary integer in computing. What is the range of unsigned int? In this article Type Name Bytes Range of Values unsigned int 4 0 to 4,/td> __int8 1 -128 to 127 unsigned […]

Why are reversible processes more efficient? Reversible processes produce the maximum amount of work If a process does work on the surroundings, you get more work out of the process if it is done slowly. This is because less heat is lost to the surroundings. So a reversible process (infinitely slow) does the maximum work. […]

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 […]
