    Wind Tunnel Power Requirements

    Its an open loop one. So about the acceleration, i have calculated the loss coefficients. And then i got the pressure drop using K=\frac{\DeltaP}{q} Where q is dynamic pressure. Does this dynamic pressure stand for the pressure required for the flow? Its Pstatic + P dynamic = P total right?

    Wind Tunnel Power Requirements

    I am designing a wind tunnel for my final year project. I am am now a little lost at the power requirements area. To select a fan, i understand that i have to overcome the pressure drops through out the tunnel by choosing a fan that has a higher pressure rise. So far i have figured out that i...

    Question about Firing tank shell in freefall

    for now I am planning to ignore that.. i just want to solve the differential equation with two unknowns and initial value. can you tell me how to solve the equation above? i have initial value for vx and vy. but where do i apply the initial values and which method should i use?

    Question about Firing tank shell in freefall

    Ok I've made a lil progress in a similar situation.. I've been trying to study projectile motion with air drag..So far i have my equations with a linear model of drag. Now i need some help. If i take a quadratic model of drag, ie f \propto v2 and in two dimensions, i get the equations from...

    Question about Firing tank shell in freefall

    ive done all those calculations. i got the idea of projectile motion today while sitting in my college bus :) I have done some calculations of the projectile motion assuming a horizontal launch with height = height of tank from the ground. (appx 304mt or 10,000ft) Now i want to add air...

    Question about Firing tank shell in freefall

    I want to ignore the parachute. Just a tank falling in free air

    Question about Firing tank shell in freefall

    Alright I'm getting the concepts. So if i calculate the drag force, it should be f=Cd * .5 * rho * A * V^2 rt. If i were to Ssume the tank in free fall, can u help me calculate the first part, the tank firing the shell sideways in x direction while falling in y direction? Thanks a lot

    Question about Firing tank shell in freefall

    Alright I see I've to use conservation of momentum. So now the velocity obtained is the velocity the tank should start moving at? If I consider air resistance, howwould I go about calculating? I can assume a coefficient of drag around 1.1 appx rt.. Another question I have is, when the...

    Question about Firing tank shell in freefall

    Im new to these forums. Hope i posted this in the right section. I watched the movie "The a-team". There is a scene where there is tank under free fall, and they fire the canon sideways to move the tank whilst free fall. I wish to calculate if this is possible or if possible, how much exact...
