How do you calculate the efficiency of an electric motor? To calculate a motor’s efficiency, you must measure its mechanical output power and divide it by the electrical input power. Measuring mechanical output power is fairly easy: You can use a torque meter to find the mechanical power based on the motor’s speed and load. […]
What is direct shear test for soil?
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?
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?
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?
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?
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?
How many integers can be represented in 32 bits?
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?
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 happens if we reverse the polarity of the diode?
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 […]
