The Blasius correlation is the simplest equation for computing the Darcy friction factor. Because the Blasius correlation has no term for pipe roughness, it is valid only to smooth pipes. However, the Blasius correlation is sometimes used in rough pipes because of its simplicity. The Blasius correlation is valid up to the Reynolds number 100000.
How much gas is present could be specified by giving the mass instead of the chemical amount of gas. Therefore, an alternative form of the ideal gas law may be useful. The chemical amount, n (in moles), is equal to total mass of the gas (m) (in kilograms) divided by the molar mass, M (in kilograms per mole): =.
This gives an LV stroke volume of 3.14 * 24 = 75.40 cc. Divide the LV stroke volume, 75.40 cc by the Aortic Valve VTI, 50 cm and this gives an aortic valve area of 75.40 / 50 = 1.51 cm 2. The weakest aspect of this calculation is the variability in measurement of LVOT area, because it involves squaring the LVOT dimension.
Domain coloring of the holomorphic tetration , with hue representing the function argument and brightness representing magnitude, for n = 2, 3, 4, ..., showing convergence to the infinitely iterated exponential between the two dots
the subscript refers to the sand fraction, s represents the ratio / where is the sand fraction density, () is the RGF as a function of the sand level within the gravel bed, is the bed shear stress available for sand transport and is the critical shear stress for incipient motion of the sand fraction, which was calculated graphically using the ...
The pelagic part of the aphotic zone can be further divided into vertical regions according to depth and temperature: [91] The mesopelagic is the uppermost region. Its lowermost boundary is at a thermocline of 12 °C (54 °F) which generally lies at 700–1,000 meters (2,300–3,300 ft) in the tropics .
One half is the rational number that lies midway between 0 and 1 on the number line. Multiplication by one half is equivalent to division by two, or "halving"; conversely, division by one half is equivalent to multiplication by two, or "doubling".
Specific gravity is defined as the density of the solvent divided by the density of water at the same temperature. As such, specific gravity is a unitless value. It readily communicates whether a water-insoluble solvent will float (SG < 1.0) or sink (SG > 1.0) when mixed with water.
