Question: problem 3 the equation for the mass flow rate of...

Question details

Problem #3. The equation for the mass flow rate of natural gas through a pipeline is determined by 4 RT The values and corresponding total uncertainties of the parameters are: m- mass flow rate (kg/s) D-pipeline diameter, 0.22t0.005 m P- absolute pressure of the gas (2200 + 60 kPa) mean velocity of the gas, 11.1 0.2 m/s R gas constant, 0.5140 kPa-m3/kg-K (exact) T- absolute temperature of the gas, 353 + 2 K Based on the given information determine: a) the total uncertainty in the mass flow rate (g/s), b) the relative uncertainty in the flow rate (%), c) which parameter uncertain contributes the greatest uncertainty to the mass flow measurement and explain how do you determined your answer.
