3. The quotient will be the speed in knots. Example: Given pitch, 18 feet; revolutions, no; apparent slip, 18 per cent. Find the speed. Operation : 18 X no = 1980. i. Oo . 18 = . 82. . 82 X 1980 = 1624. 1624 -T- 101. 3 = 16. 03 knots, ans. (3) To find the revolutions, having given the other items. From the preceding equation we derive the following value for N: , 101.^ U * ' The use of this formula will be illustrated by the following example : Given speed, 22 knots; pitch, 26 feet; apparent sl...ip, 16 per cent.

(4) To find the pitch, having given the other items. From the preceding equation we derive the following value for p. 101. 3 if P - -N(is) The use of this formula will be illustrated by the following example : Given speed, 28 knots; apparent slip, 21 per cent; revolu- tions, 380. Find the corresponding pitch.
