pipe the pressure is 2,000 psi and the elevation is 150 ft. At the outlet the elevation is
100 ft. What will be the pressure at the outlet when the temperature is 32"F? When
the temperature is 104"F?
y = (0.907)(62.4 Ib/ftg) = 56.60 Ib/ft'
A = [(2 in.)/(12 in./ft)]' = 0.0278 ft'
C = 4(2 in.)/(12 in./ft) = 0.6667 ft
