Extracted text: 2.10-7. Pressure Drop of a Flowing Gas. Nitrogen gas is flowing through a 4-in. schedule 40 commerical steel pipe at 298 K. The total flow rate is 7.40 x 10-2 kg/s and the flow can be assumed as isothermal. The pipe is 3000 m long and the inlet pressure is 200 k Pa. Calculate the outlet pressure. Ans. P2 = 188.5 kPa
