120 degrees

whats the air density for 120 degrees i live in phx az sometimes its hotter then 100 actually usually its hotter then 100 lol

If you take the equation in the course: rho(air density)=P/RxT

multiply Px144 to convert sqinches to sqfeet so..

rho=144xP/53.35(gas constant)xT or to simplify it 144/53.35 which equals 2.7

2.7xP/T is now 2.7x14.7(std air pressure)/580(degrees in Rankine)

so your Air Density given standard Air pressure and 120 degrees F is 0.068 pounds per cubic foot

Hope this helps.
