Darcy Friction Factor Calculator . For rectangular pipes (ducts), d=4a/p is known as the hydraulic diameter. Many of these types of calculations require a graphical and/or iterative solution. Head Loss (Darcy Weisbach) Calculator from ncalculators.com By definition it is four times larger than the fanning friction factor. F = 0.0055 ( 1 + (2 * 10 4 * k/d + 10 6 /re) 1/3) this approximation is valid for flow regimes where reynold's number is between 4,000 and 5*10 8, and pipes with a k/d ratio less than 0.01. Δ p f p = f d 1 2 l d i ρ w 2 = 17171 p a = 0.172 b a r.

Calculate Power Factor From Kw And Kvar . An motor is supplying a load of 700 kw at a p.f (power factor) of 0.65. To understand what the power factor correction kvar is, remember that the power factor is the ratio between real and apparent power. Power Quality Systems and Power Factor Correction Presentation from www.slideshare.net What is the difference between kvar and kw? After inputting the first two variables, the required kvar (capacitors added) to correct the load to a desired power factor can be calculated along with a compensated kva and. In a distribution system where the length unit is in miles and the construction is based on 8' crossarms, the value of x per mile ranges from about 0.7 for smaller conductors (#4, #2) to 0.6 for larger (336.4).

Factor Out Gcf Calculator . Gcf is equal to the multiplication of those prime factors. The greatest common factor calculator over here can be quite handy for you to know the gcf of two numbers easily. What I found out Factor Out The Gcf From The Polynomial Calculator from www.finance-review.com It also goes by the name greatest common divisor or highest common divisor. Let's find the greatest common factor: Order of operations factors & primes fractions long arithmetic decimals exponents & radicals ratios & proportions percent.
