Consider a two-dimensional, fully-developed, steady viscous flow of water through a duct of constant one-centimeter width in the y-direction. There is no pressure variation through the flow but the water flows in the positive x-direction, which is the direction of the gravity force. $y = 0 and gx = g. (a) Using the continuity and momentum equations, determine the magnitude of the v component of velocity and develop the ordinary differential equation that governs the u component of velocity. (b)...

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...

summarizr the followung info and write them in your own words and break them into different key points. 6.5 Metering Chamber: 6.5.1 The minimum size of the metering box is governed by the metering area required to obtain a representative test area for the specimen (see 7.2) and for maintenance of reasonable test accuracy. For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
