How is the operating point of a pump and piping system determined? The point at which a pump operates in a given piping system depends on the flow rate and head loss of that system. For example, in Figure 10, the operating point for the centrifugal pump in the original system is designated by the […]
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 […]
