Question

I want the total wet surface area of the pipe if it is more than half full 75% of its A. I only have the dia?

Answer 1

This is the second time you have tried to articulate this problem.

"half full 75% of its A."  

what does this mean?

What is "wet surface area"? Is the pipe horizontal or vertical? what is the diameter, what is the length?

Answer 2

*The surface area of the vessel that is bathed in liquid is known as the "wetted surface". The greater this wetted surface, or in other words the greater the amount of liquid in the vessel, the greater the vaporization capacity of the system.

-Inside curved surface area at 75 % full either in horizontal or vertical position. Add  bottom dish area in case of vertical pipe. Add both side dish area in case of horizontal pipe.

*Asker mean the pipe is filled with more than 50 % of the inside area, say 75%.

*If we cut the lateral face and make it flat we will get a rectangle of height

h inch and length l inch [l=3.14*diameter]

Area

=h*3.14*diameter.

=3.14 if we consider h=1 and d=1.

*A flow

= (A [full] • %A)/100

=3.14*75/100

=3.14*0.75

=2.355 inch^2

Add bottom dish area

=3.14*0.5.*0.5

=0.785 inch^2

A flow = Cross sectional Area of Flow, in^ 2

[WHEN YOUR PIPE IS 75% FULL]

A full = Cross sectional Area of Pipe, in^2

%A = Percent of Total Pipe Area.

Above is for a vertical pipe.

*For horizontal pipe area calculation ,you have to add both side dish area as the pipe is filled with water.
