1.	How is the length of the surface of a settling tank determined in case of cross- flow settling?
A.	L<sub>p</sub>=wV‚Äö√†√ú‚àö¬∫/ v cos ‚Äö√†√ú‚àö¬∫
B.	L<sub>p</sub><wV‚Äö√†√ú‚àö¬∫/ v cos ‚Äö√†√ú‚àö¬∫
C.	L<sub>p</sub>= (V‚Äö√†√ú‚àö¬∫ ‚Äö√Ñ√∂‚àö√ë‚àö¬® V sin‚Äö√†√ú‚àö¬∫)/ v cos ‚Äö√†√ú‚àö¬∫
D.	L<sub>p</sub><(V‚Äö√†√ú‚àö¬∫ ‚Äö√Ñ√∂‚àö√ë‚àö¬® V sin‚Äö√†√ú‚àö¬∫)/ v cos ‚Äö√†√ú‚àö¬∫
Answer» B. L<sub>p</sub><wV‚Äö√†√ú‚àö¬∫/ v cos ‚Äö√†√ú‚àö¬∫
