A Cylindrical Tube of Length 35m, inner radius = 2.5m
The tube is lines with 6cm thick insulation where k = 4X10^-5.
The inside temp=25 degrees celcius
Find the rate of heat delivered if the outside is -35 degrees celcius which keeps the inside temp at constant 25 degrees
The Attempt at a Solution
Im having trouble finding the Area.
A = 2(pi)rL but when I plug in the radius do I use 2.5m or do I add the 6cm thk insulation to this
