The heat loss rate Q (in W m) through a certain cylindrical pipe insulation is given by where T 1 is the temperature inside the insulation, T 2 is the temperature outside the insulation, and r 1 and r 2 are the inside and outside radii of the insulation, respectively Find the heat loss rate if T 1 145C,T 2 15 0C,r 1 1 50in , and r 2 2 50 in Q 2T (0 040)(TT) In(r r)

Question: The heat loss rate Q (in W/m) through a certain cylindrical pipe insulation is given by where T 1 is the temperature inside the insulation,

The heat loss rate Q (in W/m) through a certain cylindrical pipe insulation is given by

Q = 2T (0.040)(TT) In(r/r)

where T₁is the temperature inside the insulation, T₂ is the temperature outside the insulation, and r₁ and r₂ are the inside and outside radii of the insulation, respectively. Find the heat loss rate if T₁ = 145°C,T₂ = 15.0°C,r₁ = 1.50in., and r₂ = 2.50 in.

Q = 2T (0.040)(TT) In(r/r)
