How do you remove nitrates from wastewater? Nitrates can be removed by ion exchange using strong anionic resin in Cl- form. Reverse Osmosis is also efficient to remova nitrates, although the hydrophilic properties of the molecule does not allow an optimal removal. Biological denitrification is used in municipal waste water treatment plant. What things can […]
What color are bike lanes painted in Florida?
What color are bike lanes painted in Florida? Green Why are bike lanes painted green? Green colored bike lane surfacing is a safety feature that communicates to road users that a portion of the roadway has been set aside for preferential or dedicated use by bicyclists. What does a solid white lane mean? Solid white […]
What is total number of design parameters in the case of a four bar linkage discuss them briefly?
What is total number of design parameters in the case of a four bar linkage discuss them briefly? The four-bar linkage is a planar mechanism consisting of four rigid members: the frame, the input link, the output link, and the coupler link. These members are connected by four revolute pairs forming a closed-loop kinematic chain […]
What is linear elastic fracture mechanics?
What is linear elastic fracture mechanics? Linear elastic fracture mechanics (LEFM) is based on the analysis of cracks in linear elastic materials. It provides a tool for solving most practical problems in engineering mechanics, such as safety and life expectancy estimation of cracked structures and components. What are the conditions of Lefm? Linear Elastic Fracture […]
What are the main components of a manual clutch?
What are the main components of a manual clutch? Parts of the clutch The modern clutch has four main components: the cover plate (which incorporates a diaphragm spring), the pressure plate, the driven plate, and the release bearing. What clutch component can either engage or disengage the clutch disc and flywheel? The pressure plate is […]
What are the five stages of MIPS processor pipeline?
What are the five stages of MIPS processor pipeline? In general, let the instruction execution be divided into five stages as fetch, decode, execute, memory access and write back, denoted by Fi, Di, Ei, Mi and Wi. Execution of a program consists of a sequence of these steps. When the first instruction’s decode happens, the […]
What is a proportional flow control valve?
What is a proportional flow control valve? A proportional control valve is a valve used to control fluid flow rate by varying the size of the flow passage via a restrictor. The regulated flow rate subsequently adjusts parameters affecting a process in a system, mainly level, pressure and temperature. How do you calculate flow rate […]
What happens to the nuclear membrane during anaphase?
What happens to the nuclear membrane during anaphase? During anaphase, the sister chromatids are separated simultaneously at their centromeres. The separated chromosomes are then pulled by the spindle to opposite poles of the cell. Finally, during telophase, a nuclear membrane forms around each set of chromosomes to separate the nuclear DNA from the cytoplasm. What […]
Which raceways may be used for service entrances?
Which raceways may be used for service entrances? Rigid metal conduit (RMC) or intermediate metal conduit (IMC) are the raceway types typically used for a mast-style service entrance installation. What are 3 acceptable ways to support cable runs? Typical cable-support systems include cable trays, ladder racks, enclosed wire pathways, clamps, rings, and fasteners. How often […]
