Q1: A furnace wall riser has 22 m long, 76 mm inner diameter and 6 mm thick receives saturated water at 70 bar and 3.0 m/s velocity. Assuming that the top dryness fraction is 0.09 and the slip ratio of the two- phase mixture is 2.5, determine: (1) The pressure head developed, (11) The void fraction at the riser exit, and (iii) The heat transfer rate per unit projected area of the riser tube.
