    Calculating Maximum Water Velocity in a Draining Tank with a Guillotine Valve

    Attached drawing The set-up is simple, there is no tank on the top. I am actually draining a 3" PVC pipe that is 2.3 meters higher than the outlet. The pipe has a T where the outlet is reduced to 1.5", 2" or 2.5 inch reducers (Simple bolt on plates). When I release the valve the water...

    Calculating Maximum Water Velocity in a Draining Tank with a Guillotine Valve

    t=((A(2/g)^0.5)/Ao)(h)^0.5 This is used to calculate time to drain the tank. The h value is actually the square root of initial height - square root of final height, since final height is zero it drops out. I graph the results and take the slope of the graph at any point to get the velocity...

    Calculating Maximum Water Velocity in a Draining Tank with a Guillotine Valve

    Q Goest and gmax 137, You are exactly right, my problem is the small source size of the tank. I thought this would be a simple problem using Bernoulli's equation but I keep coming up with acceleration values for the source tank that are greater than acceleration due to gravity. Which in...

    Calculating Maximum Water Velocity in a Draining Tank with a Guillotine Valve

    I am only worried about max fluid velocity, I have data from automotive plants that suggest specific fluid velocities that I am trying to match. We are looking at creating a similar situations where beads of adhesives are placed on steel panels that are put in the water column (in order to...

    Calculating Maximum Water Velocity in a Draining Tank with a Guillotine Valve

    I am not too concerned with the type of flow, only the max velocity of the falling water column. What I am struggling with is the acceleration due to gravity. The water column should start at an intial velocity of zero, accelerate to a maximum than deccellerate due to the delta in height...

    Calculating Maximum Water Velocity in a Draining Tank with a Guillotine Valve

    Building an experimental washout tank for testing automotive adhesives. Need to calculate the maximum water velocity of the following set-up in the 3" pipe: Vertical 3" pipe approximately 3 meters high with a "T" located towards the bottom with a guillotine type valve attached to a...
