elbows, one wide open globe valve and a heat exchanger. Friction loss due to expansion and contraction is equivalent to the loss in 5.0m straight pipe. Pressure drop in heat exchanger which causes friction loss is 13900Pa., the flow rate is 0,379m3/min and pipe is 2in. Sch.40 commercial steel pipe. Length of the pipe is 50m. Draw the flowchart of the system and calculate the sum of all friction loss in this pipeline
