Carbon dioxide flows through the gas pipeline at a pressure of 0.83 MPa and a temperature of 27°C. What is the speed of gas flow in the pipe if 2.2 kg of gas flows through a cross-section of a pipe with an area of 5 cm2 in 2.5 minutes? The molar mass of carbon dioxide is 44 kg/kmol, the universal gas constant is 8300 J/(kmol*K).
