What is twinning in plastic deformation? In twinning each plane of atoms move through a definite distance and in the same direction. When a shear stress is applied the crystal will twin about the twinning plane in such a way that the region to the left of the twinning plane is not deformed where as […]
Why do engineers place tolerances on dimensions?
Why do engineers place tolerances on dimensions? Engineers place tolerance on dimensions to allow variances in an acceptable range in order to make a product function properly. The amount of tolerance depends on the degree of variations in a particular object. Why are tolerances used in engineering? Tolerance is the acceptable range for a physical […]
How do you find concentration in MLSS?
How do you find concentration in MLSS? Mixed liquor suspended solids are the solids under aeration. MLSS is measured by filtering a known volume of the mixed liquor sample, which is the same way that suspended solids are measured in wastewater. Some of the MLSS may be an inorganic material. What causes high ammonia in […]
How did humans modify the environment to build railroads?
How did humans modify the environment to build railroads? Digital Public Library of America. Human modifications include paving over vegetated areas, constructing buildings, building bridges, draining wetlands, removing or adding trees, building dams, irrigating etc. How were Native Americans impacted by the construction of the transcontinental railroad? The construction of the Transcontinental Railroad had dire […]
What is the mechanical advantage of three pulleys?
What is the mechanical advantage of three pulleys? A 3:1 pulling on another 3:1 gives you a mechanical advantage of 9:1. A system that is neither simple or compound is a complex pulley system. The 5:1 shown is a complex system. As the mechanical advantage increases, the amount of rope that must be pulled through […]
What is the equilibrium wage in this labor market?
What is the equilibrium wage in this labor market? The equilibrium market wage rate is at the intersection of the supply and demand for labour. Employees are hired up to the point where the extra cost of hiring an employee is equal to the extra sales revenue from selling their output. Why does the Monopsonist […]
What is flowmeter sensor?
What is flowmeter sensor? A flow meter (or flow sensor) is an instrument used to measure linear, nonlinear, mass or volumetric flow rate of a liquid or a gas. How does a flow sensor work? The sensor works by measuring the cooling effect of the gas passing over a thin, heated wire. The higher the […]
Is Western Blot SDS-PAGE?
Is Western Blot SDS-PAGE? SDS-PAGE is an electrophoresis method that separates proteins by mass. Western blot is an analytical technique to identify the presence of a specific protein within a complex mixture of proteins, where gel electrophoresis is usually used as the first step in procedure to separate the protein of interest. What are the […]
What are the water treatment methods?
What are the water treatment methods? Processes Chemical. Tanks with sand filters to remove precipitated iron (not working at the time) Physical. Sedimentation for solids separation that is the removal of suspended solids trapped in the floc. Physio-chemical. Biological. Desalination. Portable Water Purification. Boiler water treatment. Cooling water treatment. How do you purify wastewater? Four […]
What is technology and example?
What is technology and example? Technology is the way we apply scientific knowledge for practical purposes. It includes machines (like computers) but also techniques and processes (like the way we produce computer chips). In fact, a hammer and the wheel are two examples of early human technology. What is world technology? “The World Technology Network […]
