BTU is a unit of energy. The electrical cost is going to be proportional to the power the unit draws, so you need to look for BTU/hr. 7000 BTU/hr is going to be a higher strain than 5000 BTU/hr, for sure. You need to look at the coefficient of performance of the unit too tho.

Nigga, IQ is fucking BULLSHIT. Just apply yourself and you will be fine. Do you like math? Then by all means study it. Your success is proportional to the effort you put into it.

You dont factor the exponential, you factor the rational function that multiplies it. Then you look at a table of LTs and apply a shifting theorem.

Walls make sounds because they are not absolutely solid. Only a vibrating wall will move the air around it and make sound.

Those who study pure physics end up with a solid understanding of the theoretical fundamentals and formalism. God help them if you ask "Given a flow with average velocity V, hydraulic diameter D, and required head H, is an axial or centrifugal pump a better choice?"
