ok found what to do

How do I make excel to calculate 2 unknown from 2 equations like these a . x = 5 a. x^2 = 10 for example How do I do the setup?

did you do by this logic? Momentum of small piece + Larger piece = total mass * speed before explosion

If there are no losses you can use the formulaEnergy= 1/2 * I * W2 I= m*r2 * constant depending on shape then divide by the time you want it to reach the angular speed you want (e.g in 10 sec ...)

I couldn't find anything regarding to calculation of a bent pipe. Is there even a way other than experimenting?

It looks like the curve Radius is 50 mm and the pipe diameter before the curve is 40 mm. Is there any specific ratio to determine if the result of fixed shear rate could be negligible?

here is the shape I was talking about. Hope this helps

which has different radiuses at both end. Its actually two pipes merging after the entrance going straight and somewhere close to middle of the pipe it's bent 90°. So for simple pipes it's =4*Q π*r^3 But what for the pipe I...

[FONT=PT Sans]In here Its the same. About 9 weeks classes, then first exam, 4 weeks more lectures, 2nd exam, 2 more weeks of lecture then end with a final exam. Its mostly about memorizing especially differential equations. because I wasnt expecting it to be so but about logic I had a lot of...

I got to choose 2 lessons from these 3 for optional courses. I'm studying mechanical engineering. Which ones are the most important in your opinion? Available options are: 1) Thermodynamics II 2) Material Science II 3) Technical drawing II with CAD software ( teaches Solidworks previous year...

I think we will have to assume that they are separated as just liquid water and air with no water vapor because i couldn't find a way to find out the amount of water in air without a given humidity ratio or other info. That's why I think we should neglect it. Here's one of the sites I have...

Ok so the volume density of saturated water at 20 C is 0.001002 m^3/kg ( neglecting the small difference between compressed water at 20 C and 1 bar) and the volume density of air at 20 C and 1 bar is around 0,833 m^3 / kg Assuming we have a 1 m^3 tank we have 0,7 / 0,001002 = 698,6 kg of...

for your fifth post my reply was and for your 8th post you already pointed out the fact that makes it very complicated and that doesn't give me a clue what are the constants in here. Everything in this system are effected by the parameters
