Currently I am an undergraduate majoring in Chemical Engineering and I have two years remaining. So far I have done very well and plan on continuing to grad school after I graduate.

However, I have not been able to decide if I want to pursue a career in chemical engineering.

Is it possible to get a master's in mechanical or aerospace engineering with a bachelors in chemical?? If so, how long do you think it would take ??

We are having our thesis study.. Our study come up with a hydro power plant that has an output of 600kW.. What should be the ratings or specifications of our synchronous generator to be used (in kW or kVA)?aside from it should be a 3phase and 13.2kV rating? base to a thesis study that i read, the mini hydro power plant they designed has an output of 564,000W and they used a 250kVA, 3phase, 13.2kV synchronous generator? Is that right? can you please give me information or basis on this problem.. Can you also give me websites on where could i find the right generator, specially the pictures?thanks..

I tried hooking up a germanium diode to an amplifier circuit and then to the speaker build it didn't pick up the signal. Do I need a better amplifier to pump the signal up enough to power the speaker?

I was reading through the guiness book of world records and I noticed that the height to the roof of the Sears Tower and the height to the tip of the antennae were both higher than the height to the roof of the Petronas Towers and the height to the tip of the antennae. Yet the Petronas Towers are listed as being taller than the Sears Tower. Every source I go to lists the Petronas Towers as being taller than the Sears Tower, but the information clearly shows that the Sears Tower is taller. Does anyone know why this is?

I need help on this problem and it would be appreciated if anyone can tell me how to figure it out. There are three springs attached together in a series, with the first one attached to a wall. There is a force of 23.4 pounds pulling on the last spring. Spring 1, the one against the wall, has k1 = 20lb/in, the one in the middle, spring 2, has k2 = 32 lb/in, and spring 3, the one with the force pulling, has k3 = 12 lb/in. What is the extension of the entire arrangement of the spring system? What is the effective spring rate for the 3 springs. The answer is 3.851 inches for the extension, and 6.076 for the effective spring rate. I just don't know how to solve this.
