Question

Which is not the application of nomography?

(a) Ballistics calculations prior to fire control systems, where calculating time was critical

(b) Operations Research, to obtain results in a variety of optimization problems

(c) The design of channels, pipes and weirs for regulating the flow of water

(d) In measuring water velocity

This question was addressed to me during an online interview.

This intriguing question originated from Nomography in portion Nomography, Computer Aided Drafting & Procedure of Estimating of Civil Engineering Drawing

Answer 1

The correct choice is (d) In measuring water velocity

The best I can explain: The current velocity meter allows you to measure stream flow velocity in feet or meters per second and measure water depth in hundredths of a foot up to three feet. The average stream flow velocity times the cross-sectional area of the stream determines the stream flow measurement in cubic feet or meters per second.
