Determine the elevation change (m) between the upper and lower portions of the piping system (which is indicated on the figure as z) given that the differential pressure between the first pressure gauge and the second pressure gauge (i.e. P1 - P2) is 1500 kPa when the volumetric flow rate of glycerin is 80 L/s. Additional details on the piping system: - All the piping is 4" schedule 40 made of stainless steel - Both elbows are 90o threaded regular - The hand operated globe valve (on lower portion of piping) is fully open NOTE: Use the appropriate K values from the tables (from Janna textbook 3rd edition) given in the '08 Bernoulli Equation Part II' notes
