Chapter 1, Problem 1.36P

Pressurized water $\left(p_{in}=10\text{bar},T_{in}=110°\text{C}\right)$ enters thebottom of an $L=10\text{-m-long}$ vertical tube of diameter $D=100\text{mm}$ at a mass low rate of $\stackrel{\dot{}}{m}=1.5\text{kg/s}$ . Thetube is located inside a combustion chamber, resultingin heat transfer to the tube. Superheated steam exits thetop of the $p_{out}=7\text{bar},T_{out}=600°\text{C}$ . Determinethe change in the rate at which the following quantitiesenter and exit the tube: (a) the combined thermal andhow work, (b) the mechanical energy, and (e) the totalenergy of the water Also, (d) determine the heat transfer rate, q. Hint: Relevant properties may be obtainedfrom a thermodynamics text.
