What is the ratio of head output to the head input called? Correct Answer Efficiency of an Outlet

The ratio of head recovered (output) to the head put in (input) is known as efficiency of an outlet. If the head required for the operation that is head put in, is less more will be the efficiency. This efficiency is also a measure of conservation of head by the outlet.

In the question one statement is given, followed by two conclusions, I and II. You have to consider the statement to be true even if it seems to be at variance from commonly known facts. You have to decide which of the given conclusions, if any, follows from the given statement. Statement: A function is a relation between a set of input elements and a set of possible output elements where each input is related to exactly one output. Conclusion I: Every input element is related to every output element. Conclusion II: Every input element is related to one element of the output.
