injecting air into the spot through porous hoses or running the water through porous hoses to create air bubbles. Also there plenty of organic mater in the river so it shouldn't be hard to get the water foaming if i can create some small rapids. I'm just having trouble finding a description of...

I would be interested in how to create turbulent flow in a river to maximize the amount of white water in a spot. A more detailed explanation than just dumping object in the targeted area of the river.

Tom lynch of TomTom productions, has worked with projection art down in queens town, and he told me on the phone that the river Avon was to clear to get a decent projection off it, For water to be used as a screens for projections, it either has to be high in sediment, shallow or white capping...

converted it

how do you attach word docs to this thread

Its an idea competition we haven't settled on the river idea yet. For instance we just learned that we would need to be able to create turbulence in the shallow river to clearly project any image. The image would be moving as we want use videos of people playing basic songs on the keyboard so...

Kia ora I'm a fist year engineering student in Christchurch NZ, and a few friend and I, are designing a simple engineering report for a water projection system for an organization called gap filler. Were currently thinking of projecting an image of music onto the river Avon so people can read...

we sorted it out in the lab, thank you very much for your insight

So for example if all the resistors are 4 ohms, then R1 and R3 will be 2 ohms total and then I just add 4 ohms last as the total for the series ohms e.g. 6V Rtotal= Rs+1/Rp. 4+1/1/2 = total resistance of the circuit.

I have a lab to work through tomorrow morning and i need to be able to explain how the voltage, current and resistance in the compound circuit diagram below is distributed, and write an equation which can be used to measure the total resistance of the circuit. I know that when you normally try...

The energy lost by the catapult, I calculated the spring constant and the theoretical time and distances I calculated are large than those in reality by a factor for 10 roughly

I Have built a catapult for a 1st year engineering assignment, I know catapult are extremely energy inefficient and my theoretical catapult calculations prove that, but i don't know how to calculate the exact energy of my projectile as it hits the ground again, I can measure the projectiles real...

I figured it out I'm sorry it took so long, I went back to some articles and remembered that catapult are really energy inefficient especially my design, and once you factor that energy inefficiency percentage, all the answers made sense, I was consistently off my over a factor of 10. Thank you...

Never mind I figured it out I'm sorry it took so long, I went back to some articles and remembered that catapult are really energy inefficient especially my design, and once you factor that energy inefficiency percentage, all the answers made sense, I was consistently off my over a factor of 10...

the torsion mangonel is extremely anti kiss
