What is the exit pressure in test section of low speed wind tunnel?
In many low-speed wind tunnels, the test section is vented to the surrounding atmosphere by means of slots in the wall; in others, the test section is not a duct at all, but rather, an open area between the nozzle exit and the diffuser inlet. In both cases, the pressure in the surrounding atmosphere is impressed on the test-section flow, hence pressure will be 1 atm in the test section.
How to Calculate Test Section Velocity by Manometric Height for Wind Tunnel?
Test Section Velocity by Manometric Height for Wind Tunnel calculator uses Test Section Velocity = sqrt((2*Specific Weight of Manometric Fluid*Height Difference of Manometric Fluid)/(Density*(1-1/Contraction Ratio^2))) to calculate the Test Section Velocity, The Test Section Velocity by Manometric Height for Wind Tunnel formula is defined as a function of contraction ratio, the density of the fluid in the wind tunnel and weight per volume of manometric fluid and height difference between two sides of the manometer. Test Section Velocity is denoted by VT symbol.
How to calculate Test Section Velocity by Manometric Height for Wind Tunnel using this online calculator? To use this online calculator for Test Section Velocity by Manometric Height for Wind Tunnel, enter Specific Weight of Manometric Fluid (𝑤), Height Difference of Manometric Fluid (Δh), Density (ρ0) & Contraction Ratio (Alift) and hit the calculate button. Here is how the Test Section Velocity by Manometric Height for Wind Tunnel calculation can be explained with given input values -> 0.360159 = sqrt((2*2*0.1)/(997*(1-1/2.1^2))).
