Answer:

The correct answer for (a) is 0.9808 (b) 1.4545

Step-by-step explanation:

Solution

Considering a small cylindrical element as c.v and applying energy balance

we have,

hx Pdx [Ts - Tmx] = mCp dTm

∫^Tm0 ∫Tmi dTm/ Ts-Tmx = ∫^L ∫₀ P/mCp hx dx

Note: Kindly find an attached copy of the solution done by me, and also find the complete question to this example for the values that was inputted towards solving this question
