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?
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...
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?
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...
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...
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
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...
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...
