What is the role of the construction manager under a CM contract? The basic premise of a Construction Management (CM) Contract is that the Owner, referred to as the ‘Principal’ under the contract, enters into a contract with a Construction Manager. The Construction Manager is responsible for arranging and supervising the performance of work by […]
Which radiation is incident on outer surface of Earth?
Which radiation is incident on outer surface of Earth? Solar radiation What happens when solar radiation interacts with Earth’s surface and atmosphere? INCOMING SOLAR RADIATION Larger aerosol particles in the atmosphere interact with and absorb some of the radiation, causing the atmosphere to warm. The heat generated by this absorption is emitted as longwave infrared […]
What is the minimum working space around electrical equipment?
What is the minimum working space around electrical equipment? To be on the safe side, the working space and space around electrical equipment should always be clear per 110.26(A), if possible. As a basic rule, there should be at least 3 feet of space in front of all equipment with a 30 inch width as […]
What artery in the body has the largest diameter?
What artery in the body has the largest diameter? In the systemic circuit, blood is ejected out of the left ventricle via a single large artery—the aorta. All arteries of the systemic circulation branch from the aorta (this is the largest artery of the body, with a diameter of 2-3 cm), and divide into progressively […]
What is the difference between crystalline and noncrystalline structures in materials?
What is the difference between crystalline and noncrystalline structures in materials? The most basic difference between crystalline solids and noncrystalline solids (NCS) is that a long-range order in the distribution of atoms (ions) or molecules exists in the first case but not in the second. Any real suhstance, including noncrystalline material, is inhomogeneous regardless of […]
How would you manufacture a hammer head?
How do you put the parentheses in an equation true?
How do you put the parentheses in an equation true? Put parentheses around the first two numbers provided to create an equation; in this case (1+2) x 3-4. Use PEMDAS to determine the order of operations. PEMDAS, or Please Excuse My Dear Aunt Sally, is an acronym signifying the correct order that all math equations […]
Is a steam engine a heat engine?
Is a steam engine a heat engine? A steam engine is a heat engine that performs mechanical work using steam as its working fluid. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. Is […]
How do you find the absolute volume of concrete?
What is mean by thermal diffusivity?
What is mean by thermal diffusivity? Thermal diffusivity is the thermal conductivity divided by density and specific heat capacity at constant pressure. It measures the ability of a material to conduct thermal energy relative to its ability to store thermal energy. High diffusivity means heat transfers rapidly. What is the difference between thermal conductivity and […]
