The pressure drop occurring across the microtube is mainly composed of three parts: (1) Pressure loss along the flow path due to fluid wall friction; (2) pressure loss due to the sudden change in the pipe diameter; (3) pressure difference across the fluid interface due to capillary pressure...
The method includes measuring a high angle annular dark visual field scan type transmission electron microscope (HAADF-STEM) image of a sample, applying image processing to the measurement result to find a profile of luminance corresponding to the image, and calculating an average particle diameter ...
1.25, and 1.75 inches (19, 32 and 44 mm) or billet-stock diameters of around 1.5, 4 and 6 inches (38, 102, and 152 mm), respectively. If the length of the coil is over eight times its diameter, uniform heating at high power densities can be challenging. In cases such as these, ...
The first digit of the number π , which naturally appears when calculating the ratio between a circumference of a circle and its diameter [4], is calculated in the Old Testament [1 Kings 7:23] as 3. While in many practical situations, it is sufficient to use an approximate value, it ...
