As earlier one told that always fluid flows from high head
to lower head. It is applicable for river water. But in
the question they mentioned clearly that liquid is flowing
in the pipe. It may be connected to pump also. then head
concept is not applicable only pressure concept.


Suppose there is a sump tank. We have to transfer that
liquid into some height. for this transfer i have provided
one pump. it will transfer the liquid from lower head to
higher head.

Heat a vessel with water inside and cool it under tap suddenly. Now when we try to open it...It does not open easily ...why?
