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 as-A-(ΔT)1/4B-ΔT1/2C-(ΔT)5/4D-(ΔT)3/4-D-(ΔT)3/4

Question

The rate of heat transfer from a vertical plate by natural convection depends upon the temperature differences (&Delta;T) between wall and outside bulk. The proportionality is given as-A-(&Delta;T)1/4B-&Delta;T1/2C-(&Delta;T)5/4D-(&Delta;T)3/4-D-(&Delta;T)3/4

APTITUDE CRACK · Accepted Answer

The correct option is  D (&Delta;T)3/4 The rate of heat transfer from a vertical plate by natural convection typically follows a relationship where the temperature difference (&Delta;T) between the wall and the outside bulk is raised to a power. This relationship is commonly expressed as: Heat transfer rate&prop;(&Delta;)Heat transfer rate&prop;(&Delta;T)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&prop;(&Delta;)1/4Heat transfer rate&prop;(&Delta;T)1/4 So, the correct option is: 1/4(&Delta;T)1/4
