Formula for TPI
Can you please show me the solution of solving this problem:
A vessel 580 ft x 60 ft, with a waterplane coefficient of 0.84 is floating in freshwater at a draft of 21 feet. How many long tons shall it take to increase the mean draft by 1 inch?
Answer (According to our reviewer): 67.6 tons
Solution:
Step 1. Multiply the ship's length by it's breadth and then by its water plane coefficient.
580 ft x 60 ft x 0.84 = 29, 232 square feet. This is your area of water plane.
Step 2. Divide your area of water plane by 432 since the ship is floating on freshwater.
29232 ÷ 432 = 67.6 is your TPI

ReplyDeletea box-shaped vessel 60 meters long,11 meters wide with a depth of 8 meters has an empty amidship compartment 12 meters long. the vessel is on an even keel 3.80 meters. calculate the increase in draft if the compartment is bilged.
