Question

The average heat transfer co-efficient for laminar film condensation on vertical surface is inversely proportional to (where, &Delta;T = Temperature drop across condensate film )-A-(&Delta;T)2B-&Delta;TC-(&Delta;T)1/4D-(&Delta;T)3/2-C-(&Delta;T)1/4

APTITUDE CRACK · Accepted Answer

C (&Delta;T)1/4 The average heat transfer coefficient for laminar film condensation on a vertical surface is inversely proportional to the temperature drop across the condensate film (&Delta;T) raised to the power of 1/4 (&Delta;1/4&Delta;T1/4). Mathematically, it can be represented as: ℎavg&prop;1()1/4havg​&prop;(&Delta;T)1/41​ Therefore, the correct option is: (&Delta;)1/4(&Delta;T)1/4.
