Heat Transfer Harmonic mean temperature difference is given by √(ΔT₁ . ΔT₂) 2.(ΔT₁ . ΔT₂)(ΔT₁ - ΔT₂) 2.(ΔT₁ . ΔT₂)/(ΔT₁ + ΔT₂) (ΔT₁ - ΔT₂)/(ΔT₁ . ΔT₂) √(ΔT₁ . ΔT₂) 2.(ΔT₁ . ΔT₂)(ΔT₁ - ΔT₂) 2.(ΔT₁ . ΔT₂)/(ΔT₁ + ΔT₂) (ΔT₁ - ΔT₂)/(ΔT₁ . ΔT₂) ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer In a laboratory test run, the rate of drying was found to be 0.5 x 10-3 kg/m².s, when the moisture content reduced from 0.4 to 0.1 on dry basis. The critical moisture content of the material is 0.08 on a dry basis. A tray dryer is used to dry 100 kg (dry basis) of the same material under identical conditions. The surface area of the material is 0.04 m²/kg of dry solid. The time required (in seconds) to reduce the moisture content of the solids from 0.3 to 0.2 (dry basis) is 5000 6000 4000 2000 5000 6000 4000 2000 ANSWER DOWNLOAD EXAMIANS APP
