Q6. The following data applies to a ship operating on a particular voyage with a propeller of 6 m diameter having a pitch ratio of 0.95:
Propeller speed = 1.8 revs/s
Real slip = 34%
Apparent slip = 7%
Shaft power = 10000 kW
Specific fuel consumption = 0.22 kg/kW-hr
Calculate EACH of the following:
(a) The ship speed in knots;
(b) The Taylor wake fraction;
(c) The reduced speed at which the ship should travel in order to halve the voyage consumption;
(d) The voyage distance if the voyage takes 3 days longer at the reduced speed;
(e) The amount of fuel required for the voyage at the reduced speed.
