A 310,00 GRT vessel needs to achieve a steady speed of 13 knots after exiting a canal. If
the speed of the vessel before exiting the canal is 3 knots, calculate the time (in minutes)
to reach the desired speed assuming that her acceleration is 0.08 knots per minute.
Convert the acceleration of the vessel to knots per hour (round up answer to 2 decimal
places)
To calculate the time it takes for the vessel to reach the desired speed, we can use the formula:
time = (desired speed - initial speed) / acceleration
Given:
GRT vessel = 310,000 GRT
Initial speed = 3 knots
Acceleration = 0.08 knots/minute
Desired speed = 13 knots
time = (13 - 3) / 0.08
time = 10 / 0.08
time = 125 minutes
To convert the acceleration to knots per hour, we multiply it by 60 (since there are 60 minutes in an hour):
acceleration (knots/hour) = acceleration (knots/minute) * 60
acceleration (knots/hour) = 0.08 * 60
acceleration (knots/hour) = 4.8 knots/hour
Therefore, the acceleration of the vessel is 4.8 knots/hour.
