WebMar 5, 2024 · Open 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. WebThe head loss (or the pressure loss) due to fluid friction (H friction) represents the energy used in overcoming friction caused by the pipe walls. The head loss that occurs in pipes is dependent on the flow velocity, pipe diameter, and length, and a friction factor based on the roughness of the pipe and the Reynolds number of the flow. A ...
WebThe flow-related signal is a pressure difference, measured between the two points on the meter body as shown in Figure 2. These meters accelerate the fluid stream by imposing a contraction on the flow area, and then decelerate the flow, by expanding back to the original pipe diameter. As the fluid accelerates, its static pressure is reduced.
