Heat Transfer The variation of thermal conductivity of a metal with temperature is often correlated using an expression of the form K = K₀ + at. where, K is the thermal conductivity and T is the temperature (in °K). The units of 'a' in SI system will be None, A is just a number W/m W/m.k W/m.k² None, A is just a number W/m W/m.k W/m.k² ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer Fouling factor for a heat exchanger is given by (where, U₁ = heat transfer co-efficient of dirty surface U₂ = heat transfer co-efficient of clean surface) U₁ - U₂ 1/U₁ - 1/U₂ U₂ - U₁ 1/U₂ - 1/U₁ U₁ - U₂ 1/U₁ - 1/U₂ U₂ - U₁ 1/U₂ - 1/U₁ 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 4000 5000 2000 6000 4000 5000 2000 6000 ANSWER DOWNLOAD EXAMIANS APP
