If the flow rate is tripled to 150,000 bbl/day, the Reynolds number becomes 3570 and the flow will be in the critical region. At flow rates above 168,040 bbl/day, the Reynolds number exceeds 4000 and the flow Zero is considered to be both a real and an imaginary number. As we know, imaginary numbers are the square root of non-positive real numbers. And since 0 is also a non-positive number, therefore it fulfils the criteria of the imaginary number. Whereas 0 is also a rational number, which is defined in a number line and hence a real number.The House GOP conference selected Jordan on Friday as its latest speaker-designee in a 124-81 vote over GOP Rep.
