How do you calculate the mass flow rate, volume flow rate and velocity of a 6 bar compressed air supply through a 2mm tube? This is all the information I have been given. Is there any theory that could help me here? I can't seem to find much on the internet, so I have no clue where to begin...

Homework Statement I have this object avoidance robot, who is supposed to detect cans and push them out of a ring. It has two optical sensors, one looking left (C1) and one looking right (C2). I also have two timers which are triggered simultaneously when the robot goes over the ring line...

I've done it now thanks! But how do I calculate the heat rejected? :/

An ideal simple gas turbine has a compression ratio of 5. What is its efficiency? If the turbine produces 6 MW (gross) and the compressor requires 2 MW to drive it, what is the work ratio and how much heat is rejected?

Yeah: "The turbine produces 6 MW (gross) and the compressor requires 2 MW to drive it." It's just put after the question, so I assumed I need to use the compression ratio which is 5.

Homework Statement An ideal simple gas turbine has a compression ratio of 5. What is its Homework Equations c=r(γ-1/γ) η=1-(1/c) The Attempt at a Solution I'm stuck, I think I need to use the above equations and possibly more. I just don't know how to find a value for the ratio of...

a+ib=[(3+i)/(5+i)]5 Thanks.

y=1+x+x3I just don't know where to begin... I've always struggled with domains and ranges. Even if you could just point me in the right direction, that would be great! Thanks.

Okay...I've expressed my answer as: y=1/2[a-(x2/a)] Is that a better way to express it?

Find the Cartesian Form of r(1+sinθ)=a I understand that: x=rcosθ y=rsinθ and r2=x2+y2I can get quite far to the point I end up with x2=a2-2ay I'm struggling to eliminate "a"...

I have the set of values for resistors available: 10-12-15-18-22-27-33-39-47-56-68-82 And I need to get a gain of 15, which values should I use to get this? Also, I have a non-inverting amplifier, and again, I need a gain of 15. I selected the values: R2=12 and R1= 68+82+18=168 I assumed I was...

Just wondering what the name of the component as a whole is? And what is it made of? Also, if you could tell me the name of all the constituent parts, that would be great...
