WebInstitute of Physics WebOpen the bench valve and set the flow at the maximum flow in Part A (i.e., 17 liter/min); fully open the gate valve and flow control valve. Adjust the gate valve until 0.3 bar of head difference is achieved. Determine the volumetric flow rate. Repeat the experiment for 0.6 and 0.9 bars of pressure difference. 9. churches in middleton idaho

WebMinor pressure and head loss in pipes vs. equivalent length in tubes and duct systems. Pressure loss in straight pipes or ducts are called the major, linear or friction loss. Pressure loss in components like valves, bends, tees and similar are called the minor, dynamic or local loss. Minor loss can be significant compared to major loss. Webwhere for ball valves, k = 1.35; and butterfly valves, k = 1.85.
