Extracted text: 8. N2 is usually used in spray painting guns as an atomizing gas. Tank 1 with a volume of 5 m3 is periodically filled withdrawing the gas from storage tank 2 of larger volume maintained at 25 atm. The line connecting the two tanks is composed of 50 m long and pipe diameter of 0.05 m. a. Calculate the volumetric flow in m³/s transferred when the shut-off valve between the two tanks is opened. Note that the initial pressure of tank A is equal to atmospheric pressure with a constant temperature of the gas at 293.15 K. b. Calculate the mass to be transferred from B to A to load the tank A up to a pressure of 15 atm at the same constant temperature.
