AI Thread Summary
The discussion focuses on applying the superposition theorem to a double loop circuit with two batteries and three resistors. Loop 1 includes an 8V battery with 8 Ohm and 6 Ohm resistors, while Loop 2 has a 9V battery with a 6 Ohm and 3 Ohm resistor. Participants are encouraged to share their equations and identify where they are stuck to facilitate assistance. Additionally, there is a separate inquiry about calculating the heat supplied per kilogram and the thermal efficiency of a heat exchanger. The conversation emphasizes the need for clarity in problem-solving to achieve accurate results.

I have two batteries and three resistors in a double loop circuit, Loop 1 is a 8V battery and res 1 is 8 Ohms and the res 2 is 6 Ohms need to work out super position theorum for that then the second loop is res 2 is 6 Ohms and res 3 is 3Ohms and the battery is 9V, need to work out the super position theorum for that then using kirchhoffs law i have to check both and confirm that i get the same values. Can anyone help please.

hi dawsond78! welcome to pf! :wink:

Show us the equations you have, and where you're stuck, and then we'll know how to help! :smile:
 


[i have a question i am stuck on,
" The input power of a heat exchanger is rated at 5.56MW and is supplied with water at 37 Degrees C. The exchanger heats the water to 100 Degrees C, at which point it is turned into dry stream. The dry steam is then supplied by the heat exchanger at 1.6 kg/s.
The specific heat capacity of water is 4.19kJ/kgK and the specific latent heat of vaporisation is 2.25Mj/K"

1. find heat supplied/kg
2.thermal efficiency of the heat exchanger


Can anyone help me please]
