How is a bimetal strip made?
How is a bimetal strip made? The strip consists of two strips of different metals which expand at different rates as they are heated, usually steel and copper, or in some cases steel and brass. The strips are joined together throughout their length by riveting, brazing or welding. How are bimetallic strips used in thermostats? […]

Where scaffold platforms are more than 24 inches above or below a point of access a means of access shall be provided? Direct access to or from another surface shall be used only when the scaffold is not more than 14 inches (36 cm) horizontally and not more than 24 inches (61 cm) vertically from […]
What is the friction factor for turbulent flow?
What is the friction factor for turbulent flow? The friction factor or Moody chart is the plot of the relative roughness (e/D) of a pipe against the Reynold’s number. The blue lines plot the friction factor for flow in the wholly turbulent region of the chart, while the straight black line plots the friction factor […]
How does the crystalline state differ from the amorphous state?
How does the crystalline state differ from the amorphous state? Crystalline solids have well-defined edges and faces, diffract x-rays, and tend to have sharp melting points. In contrast, amorphous solids have irregular or curved surfaces, do not give well-resolved x-ray diffraction patterns, and melt over a wide range of temperatures. How can a crystalline solid […]
What is a solid solution alloy?
What is a solid solution alloy? An alloy is a mixture or metallic-solid solution composed of two or more elements. Examples of alloys include materials such as brass, pewter, phosphor bronze, amalgam, and steel. Complete solid solution alloys give single solid phase microstructure. What is solid solid solution? Solid solution, mixture of two crystalline solids […]
How does ion exchange method remove hardness of water?
How does ion exchange method remove hardness of water? Ion exchange involves removing the hardness ions calcium and magnesium and replacing them with non-hardness ions, typically sodium supplied by dissolved sodium chloride salt, or brine. What do you mean by ion exchange? Ion exchange usually describes a process of purification of aqueous solutions using solid […]
