Viscous fluid flow 2nd edition Frank White
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 transfer (dQ/dt) through the pipe walls between entrance and exit. How would one nondimensionalize this heat transfer rate? Hint: The continuity or mass-balance part of Prob. 2-14 must be solved first.
For Non-dimensionalization of heat transfer rate Q' one choice can be
**Please Note that in the image I have written dQ/dt as Q'

just now i sent this questions. this is the answer given. however the answer i afraid that he used formula that is not for constant surface temperature and noncircular formula. this is the formula foe the noncircular tube. because the question ask about triangle. my problem is, i cannot answer question 1(b) that ask the heat transfer coefficient, h. please help me. thank you. this pic is a note on constant surface temperature. page 482 ref: HEAT AND MASS TRANSFER:...
Alt 9) Gas A, in fully developed, laminar air flow, enters a tubular inhaler of A in radius and I in reacts at the inner wall of the inhaler to fom gas B. The per unit area is-r.-k"C. To obtain the Ca profile we do the shell rate of A balance of mass transfer, where the generation term is a catheter of radius Rc placed in a small artery of radius R as shown the moves at a constant speed...
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...
