GIVE ME THE Numerical value not the formula.. WHATS THE ANSWER IN OHMS ?? Give answer as a Number NOT EQUATION 

Sir, I need more details. Thanks

From the picture of panel  name plate, explain each and every parameter displayed in it in a brief manner.

We are running 3 wires and a ground in a RMC to a control panel with a 60 amp circuit breaker disconnect in the control panel. The conduit is run along the ceiling where the ambient air temperature is 100 degrees. The control panel feeds our secondary cooling pump. What size are the ungrounded conductors? All conductors have typeTHHN insulation. A   #6 AWG B   600 Kcmil C   #8 AWG D   #2 AWG What size RMC do we need? A   3" B   3/4" C   1" D   1 1/2"
