A pipe reduces it size from 300mm diameter at point 1, to 100mm diameter at point 2. The pressure at point 1 is 200KPa, and point 2 is 7m higher in elevation than point 1. The discharge on the pipe is 30 L/s and the head loss from point 1 to 2 is 10% of the pressure head at point 1. Determine the pressure at point 2 if a) the liquid is water, b) if the liquid is oil (SG = 0.8) and c) if the liquid is glycerin (SG = 1.3)
