Computation Of LRA

Shh.

There is no way to tell.

I assume that you mean tons of cooling.

That would be 12,500 BTUs per hour. You need to know a whole lot more than what you have given us.

TURN OFF CAPS LOCK!!!!!!!!!!!

I don't know. What does your textbook say about conversion of electric power to air-conditioning capacity? How does this tie into Linear Regression Analysis?

Lastly, typing in all capital letters is considered to be SHOUTING AND RUDE! Please turn your "caps lock" off.

Thank you for being polite.

RLA ≈ LRA/8 to LRA/6.
For HVAC, TR ≈ 1.0 to 1.2 x HP.
1 HP = 746 W.
For 1Φ, W = V x RLA; for 3Φ, W = √3 x V x RLA.
