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. WebGas will always flow where there is a difference in pressure. Δp = (p 1 – p 2) > 0. The intensity of the gas flow, i.e. the quantity of gas flowing over a period of time, rises with the pressure differential. In the case of viscous flow, however, this will be the case only until the flow velocity, which also rises, reaches the speed of sound. howden uk limited
