(2) Using the equation shown in the lecture notes, compute the pressure drop required for the gas pipeline shown below AND compute the pressure that would be added if kinetic energy was added in. The line is over flat terrain. You may use the PPS software to estimate fluid properties. 2 1 2 g 10,000 MScf/Day 5 miles 3.00" ID 500 psi 100 deg F 60 deg F 0.65 q L d p T T γ = = = = = = = The solution equation for horizontal flow is: 2 2 2 4 2 1 5 1.007 10 g fzTq L p p x D - = - Since the inlet pressure is not known the average z is not known.
