90+% Efficiency Gas Furnace - Gas Furnaces Bryant
WebThe heat exchanger is used to heat a cold fluid from 120°F to 310°F. Assuming that the hot fluid enters at 500°F and leaves at 400°F, calculate the LMTD for the exchanger. Solution: ΔT 2 = 400°F − 120°F = 280°F ΔT 1 = 500°F − 310°F = 190°F Δ T l m = ( Δ T 2 − Δ T 1) ln ( Δ T 2 Δ T 1) = ( 280 ∘ F − 190 ∘ F) ln ( 280 ∘ F 190 ∘ F) = 232 ∘ F http://www.madehow.com/Volume-7/Furnace.html images of vizsla dog
