When the stream line Streak line and path line will be same? For a steady flow, all above mentioned three lines, viz. streamline, path line and streak line are identical. Streamline– A streamline is an imaginary line drawn through a flowing fluid in such a way that the tangent to it at any point gives […]
How are single crystal turbine blades made?
How are single crystal turbine blades made? A common method is the Bridgman method to grow single crystals. In this method a casting furnace is used for crystal growth. In this process, a mould must first be made of the blade. Molten wax is injected into a metallic mould of the desired turbine blade and […]
What are the advantages of DSB-SC?
What are the advantages of DSB-SC? The advantage of DSB-SC modulation is its consumption of low power as obtained in overcoming the shortcomings faced by other modulation due to suppressed carrier in this modulation. What are the applications of DSB-SC? Applications of DSB-SC modulation During the transmission of binary data, DSB-SC system is used in […]
What is the unit of Rockwell hardness number?
What is the unit of Rockwell hardness number? The Rockwell C scale is usually abbreviated HRC (Hardness Rockwell C), while the Rockwell B scale is abbreviated HRB (Hardness Rockwell B). The higher the number, the harder the material, but only relative to other numbers within a given scale. What are the units of hardness? HARDNESS […]
How do I write a risk assessment report?
How do I write a risk assessment report? Step 1: Identify the hazards. Step 2: Decide who might be harmed and how. Step 3: Evaluate the risks and decide on precautions. Step 4: Record your findings and implement them. Step 5: Review your risk assessment and update if. How you would undertake a risk assessment? […]
What are the 3 methods of heat transfer?
What are the 3 methods of heat transfer? Heat is transfered via solid material (conduction), liquids and gases (convection), and electromagnetical waves (radiation). Heat is usually transfered in a combination of these three types and seldomly occurs on its own. What is steady state in heat transfer? When we say a steady state is reached, […]
What is the composition of tungsten carbide?
What is the composition of tungsten carbide? Properties and Applications Tungsten carbide (WC) is an inorganic non-natural compound composed of tungsten (W) and carbon (C). Mono-tungsten carbide (WC), which is stable at room temperature, is of major technical relevance. WC exhibits a hexagonal structure made of a grid of tungsten and carbon. What are carbide […]
How do you know if you have a high or low pass filter?
What happens when a solution is neutral?
What happens when a solution is neutral? Deciding if a Solution is Neutral A solution is neutral if the concentration of hydrogen ions in solution is the same as the concentration of hydroxide ions in the solution. What substance does a neutral substance release? What substance does a neutral substance release? No substance. A neutral […]
How is uniaxial stress calculated?
How is uniaxial stress calculated? Uniaxial Deformation simply means that you push or pull in one direction only….Science of Uniaxial Deformation σ = stress = force per area. ε = strain = (l(σ) – l0)/l0. dε/dt, the derivative of the strain with respect to time t, is the strain rate. What is uniaxial stress? A […]
