Then, continue writing the electron configuration of a certain element until you reach the correct number of electrons. The capacity of a low pressure natural gas (less than 1 psi, 6.9 kPa) pipe line with a small pressure loss can be calculated with the Spitzglass formula. Because Re depends on the velocity of the fluid defined by its flow rate, it is not possible to know Re until it is already calculated, which means that after Q is calculated, Re should be verified. How is the calculation performed? Velocity is nothing but rate of change of the objects position as a function of time. cu-ft/min, Million standard cubic feet per day MMSCFD - mil.
