When a vacuum is applied to a standard cubic foot of gas, it expands. The volume of gas after it is pressurized or rarefied is referred to as its actual volume. The term cubic feet per minute (CFM) is ambiguous when it comes to the mass of gas that passes through a certain point because gas is compressible. If the pressure is doubled, then, for an ideal gas, the mass of the gas that passes by will also be double for the same rate of flow in cubic feet per minute.
Intel Xeon Phi 7290 Features 72 Cores Running At A Clock Speed Of 1.5GHz â Its Also Intelâs Most Expensive Chip. Intel Xeon Phi 7290 runs at a base clock speed of 1.5GHz and features 72 processing cores, which is Intelâs fastest and might we add, most expensive chip to date. According to the company, the Xeon Phi will commence shipment from the month of September, and will also carry a massive price tag of $6,294.
From the graphic one can see that it looks like a wave, and in truth sines (and cosines) come as solutions of a number of wave equations, where the variable is a function of space and time. here phi ($\phi$) is a phase . It is a constant that tells at what value the sine function has when $t=0$ and $x=0$. If one happens to have two waves ovelapping, then the $\phi_1$-$\phi_2$ of the functions is the phase difference of the two waves. How much they differ at the beginning ($x=0$ and $t=0$), and this phase difference is evidently kept all the way through. share | cite | improve this answer.
