Questions and Answers

What is the primary function of a towing tank in the calibration of current meters?

To move a carriage longitudinally over its surface at constant speed to determine the average value of revolutions per second of the instruments.

What is the purpose of sounding weights in current meter measurement?

To enable the current meter to be positioned in a stable manner at the required location in flowing water.

What is the formula used to estimate the minimum weight of a sounding weight?

W = minimum weight in N, where W = v^2 * d.

What is the principle of the float method for measuring velocity?

<p>The floating object on the surface of a stream is timed to yield the surface velocity by the relation S = distance travelled in time t.</p> Signup and view all the answers

What is the advantage of using a towing tank for calibration of current meters?
