In this article, the following conventions and definitions are to be understood: The Reynolds number Re is taken to be Re = V D / ν, where V is the mean velocity of fluid flow, D is the pipe diameter, and where ν is the kinematic viscosity μ / ρ, with μ the fluid's Dynamic viscosity, and ρ the fluid's density.
If Swamee-Jain, etc., is usually written in terms of 'f' instead of '1/sqrt(f)' then it might cause confusion to _replace_ the usually-expected form with a revised form. While the '1/sqrt(f)' form is traditional for the Colebrook equation, the other equations which calculate 'f' seem more user-friendly to me in that they don't require the user ...
Additionally, an angle that is a rational multiple of radians is constructible if and only if, when it is expressed as / radians, where a and b are relatively prime integers, the prime factorization of the denominator, b, is the product of some power of two and any number of distinct Fermat primes (a Fermat prime is a prime number one greater ...
r = | z | = √ x 2 + y 2 is the magnitude of z and; φ = arg z = atan2(y, x). φ is the argument of z, i.e., the angle between the x axis and the vector z measured counterclockwise in radians, which is defined up to addition of 2π. Many texts write φ = tan −1 y / x instead of φ = atan2(y, x), but the first equation needs ...
The former first lady was notably absent from President Jimmy Carter's state funeral service, leading Barack Obama and Donald Trump to be seated next to one another
A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]
Entering Thursday, Butler is averaging 18.5 points, 5.8 rebounds and 4.9 assists in 20 games (all starts) this season while shooting a career-best 55.2 percent from the field.
