A pipeline has been proposed to carry natural gas 1715 miles from Alaska's North Slope to Calgary, Alberta, Canada. The (smooth) pipe diameter will be 52 inches. The gas will be at high pressure, averaging 2500 lbs/in². Why? The proposed flow rate is 4 billion cubic feet per day at sea-level conditions. What volume flow rate, at 20°C, would carry the same mass at the high pressure? If natural gas is assumed to be methane (CH4), what is the total

Question 4
a) A pipeline has been proposed to carry natural gas 1715 miles from Alaska's
North Slope to Calgary, Alberta, Canada. The (smooth) pipe diameter will be
52 inches. The gas will be at high pressure, averaging 2500 Ibs/in?. Why? The
proposed flow rate is 4 billion cubic feet per day at sea-level conditions.
What volume flow rate, at 20°C, would carry the same mass at the high
pressure? If natural gas is assumed to be methane (CH4), what is the total
pressure drop? If each pumping station can deliver 12,000 hp to the flow,
how many stations are needed?
