  1. The thermal conductivity of a nonwoven fabric is given by 
    λ = 0.03 + 0.00005ρ + 0.15/ρ 
    where λ is the thermal conductivity of the fabric in W/(m⋅K), ρ is the bulk density of the fabric in kg/m3, and ρ∈[10,200].
    Thermal conductivity is minimum when the bulk density is approximately
