Homework Statement This is not really a homework question but just need to know how to re arrange the virial equation to solve for volume Homework Equations PV/RT = 1 + B/V +C/V2 The Attempt at a Solution How can I re arrange this equation to solve for V?

Homework Statement Ammonia NH3 is made by the haber process: N2 + 3H2 --> 2NH3 The nitrogen required for this process is obtained from air by using the air to burn natural gas CH4 , thereby removing the oxygen from the air, leaving behind only nitrogen. The hydrogen required is obtained...

Thank you for your help One question though, when working out the final step of this problem to find the power of the combined loads, do I use the total resistance, or just the load resistance?

Homework Statement A 48 V DC wind turbine is hooked up to charge a battery bank consisting of four 12 V batteries in series. The wind is not blowing, but the batteries must supply 2 loads. One is a light bulb, rated at 175 W at 48 V; the other is a heater, rated 1000 W at 48 V. The loads are...

I am having difficulty trying to rearrange this equation to solve for one unknown variable. i=(io)exp(z*α*F*∆V)/(R*T) How would I rearrange this equation if i wanted to solve for io, also how would I rearrange this equation to solve for say α.

Just divide 70 A-h by the 15 A, the A cross themselves out and your left with just the hours not necessary to switch to coulombs.

alright I think I figured out the first problem w=m x g x deltaz =(400L/day)(9.81m/s^2)(7m) = 27468 J/day (27468/3.6 x 10^6) x 0.065 =$0.00049 the second one I'm still having problems with i think the equation is PV=NrT so it would be P=nr(25 C)/100L I'm just not sure what N...

Hi I am stuck on two questions here not sure if this is the right part of the forum to post it in, sorry in advance if it isn't. Ok the questions, my problem is that I'm not sure on the equation to use to solve these problems first problem is A solar water heater utilizes a pump to lift...
