OS QUESTION 3 Suppose that a methane gas flows in pipeline 1000 m long with 0.1 m inner diameter. The pipe carries 0.7 kg/s of methane at a constant temperature of 0 C. The molecular weight and viscosity of methane gas can be taken as 16 g/mol and 1.02x10-5Pass, respectively. The material of construction of the pipe is commercial steel and may be assumed to be horizontal. If the outlet pressure is 105 kPa, calculate the inlet pressure Tot
