1.The West Panhandle Gas Field is in the panhandle of Texas. Atmospheric pressure in the area averages about 13.2 psia. What are the standard conditions used to calculate gas quantities produced from this field? A pressure gauge on a wellhead reads 47.0. What is the pressure in psia? What is the pressure in atmospheres (absolute)?
2.Calculate the extreme-fibre stresses at mid-span for a simply supported prestressed concrete beam with a depth of 750mm, width 370mm and span of 7m under working live load of 65 kN/m and self-weight. The prestressing force, P = 2000kN, is applied through a parabolically draped tendon with a maximum eccentricity at mid-span of 150mm and zero eccentricity at the ends.
