I need answer of 2.17
I have attached 2.14 question and solution for reference.
2.17 As an extension of Prob. 2-14, consider the heat-transfer
aspect by assuming a uniform entrance profile T = To and an exit
profile approximated by T(r) = T0(1.5 + 0.5r2/ri). For flow with
constant (p, F, cp, k) and negligible kinetic- and potential-energy
changes, use the integral relations to compute the total heat...

Homework 2 Problem 1: A piston-cylinder device initially contains 0.35-kg steam at 3.5 MPa, superheated by 7.4 C. Now the stream loses heat to the surroundings and the piston moves down, hitting a set of stops at which point the cylinder contains saturated liquid water. The cooling continues until the cylinder contains water at 200C. Determine (a) the final pressure and the quality (if mixture), (b) the boundary work, (c) the amount of heat transfer when the piston first hits...
