Heat Transfer - Engineering
Q1: The rate of heat transfer from a vertical plate by natural convection depends upon the temperature differences (ΔT) between wall and outside bulk. The proportionality is given asA (ΔT)1/4
B ΔT1/2
C (ΔT)5/4
D (ΔT)3/4
ANS:D - (ΔT)3/4 The rate of heat transfer from a vertical plate by natural convection typically follows a relationship where the temperature difference (ΔT) between the wall and the outside bulk is raised to a power. This relationship is commonly expressed as: Heat transfer rate∝(Δ)Heat transfer rate∝(ΔT)n The value of the exponent n depends on the specific conditions of the natural convection process. For a vertical plate, the relationship between heat transfer rate and temperature difference is often given as: Heat transfer rate∝(Δ)1/4Heat transfer rate∝(ΔT)1/4 So, the correct option is: 1/4(ΔT)1/4 |
