WebIf the flow rate, specific heat and temperature difference on one side are known, the heat load can be calculated. Calculation method. The heat load of a heat exchanger can be derived from the following two formulas: 1. Heat load, Theta and LMTD calculation. Where: P = heat load (btu/h) m = mass flow rate (lb/h) c p = specific heat (btu/lb °F)

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 hertz shelby rental carWebAnother important 1D heat transfer problem is that of a semi-infinite body with a surface thermal condition—temperature, heat flux, or convection boundary conditions.
