Q1: If average heat transfer co-efficient is h_a and the local coefficient at the end of the plate is h_l then in case of heat transfer to a fluid flowing over a flat plate, heated over its entire length

ANS:B - h_a = 2h_l

In the case of heat transfer to a fluid flowing over a flat plate, heated over its entire length, the average heat transfer coefficient (ℎ​) is related to the local coefficient at the end of the plate (hl​) by the following relationship: ha​=0.75⋅hl​ So, the correct answer is: "ha = 0.75 hl"
