Answer / rajasekar
Ball is fixed in the tip of the pen. Ball is rotated by the
friction with paper.due to capillary action (the gap
between ball and ball holder is min) the ink flows between
ball and ball holder and it is printed on the paper.

Q : How to calculate cooling water pumps head, do I need to consider static head and frictional loss of the pipe with high elevation? I mean to say is discharge pipe branches to several elevations and joins to the cooling water return line. The highest elevation pipe goes to a heat exchanger at (xx) psi inlet pressure. Should I consider only pump discharge header and this piping for head calculations? How about frictional losses in return pipe? Pressure recovered in return piping is good enough to make it back to the cooling tower?
