Given the diagram below, determine the sum of the K factors for the system. Assume: 1. The valve identified as a fully open butterfly valve is actually a disk value open 2/5 of the way. 2. The 3-inch pipe is 4-inch. 3. All connections are regular and flanged. 4. The flow is fully developed turbulent flow. Flow 3-in coated ductile iron pipe Total length = 55 m 6-in coated ductile iron pipe Total length = 30 m Sudden enlargement B Butterfly valve 10 m
