Dpipe $19\mathrm{.}8$ mm

Condensation plays an important role to increase the energy efficiency in HVAC industries You are an engineer working on a project in HVAC industry. The current condeneing unit of your profoct ste has a condensing pipe made of Aluminum alloy. The outer diameter of the bare pipe is $19\mathrm{.}8$ mm $.$ The sensor reading indicates that the steam inside the plpe is at a pressure of $9\mathrm{.}9$ bar. You noticed that the condensation pipe needs an increase in surface area to enhance the heat transfer process. You pian to install annular fins on the bare pipe. You selected annular fins which are made up of atuminum alloys due to its higher thermal conductivity after copper which is a risky choice due to corrosive environment. It is one of the most widety used materials for manufacture of fins. The specifications of the fins are shown in the figure. An important design parameter is to find out the condensation rate through the pipe $($kg$/$hour$).$ The atmospheric Temperature around the pipe is at is $17\mathrm{.}5C$ and the heat transfer coefficient is $5\mathrm{.}9\frac{W}{m^2}C.$

$($a$)$ Find: Mass flow rate of the condensation $($kg$/$hour$)$ through the pipe after the installation of fins?

$($D$)$ What strategies can you implement to enhance the quantity of condensate? Please share your ideas

$($c$)$ If you had the option to choose a different type of fins, which one would you select and Why?

Hints: $($a$)$ Follow the method demonstrated in class to calculate the total q$.$ Once you have determined this total $q,$ use it to find the condensation rate. You will need some information from the properties table that has been supplied.

Part $($b$)$ and $C),$ are open ended questions, you are free to answer part b$,$ c either by providing theoretical reasons or showing some calculations.

Do NOT count the number of fins from the figure
