SITUATION 5
An Evergreen's rectangular barge with 6750 m² horizontal cross-
sectional area at the water line has a draft of 12.58 m in sea water
(10.05 kN/m³) when loaded to capacity. In the freshwater at the
entrance of the Panama Canal, it was observed that ship draws 12.89
m. Unit weight of water is 9.80 kN/m³.
11. What is the weight of the barge and its cargo in kN?
a. 865,250
c. 912,360
b. 824,360
d. 799,650
12. What is the displacement of the barge in freshwater in m³?
a. 86,458
c. 84,119
d. 102,102
b. 92,226
13. With an available water depth in the canal of 12.75 m above the
lock sills, how many kN of carge must the barge be relieved so
that it can barely pass into the locks with 90 mm clearance below
the keel?
a. 16,325
c. 19,995
d. 15,215
b. 14,785
SITUATION 6
The hull of a boat has a volume of 180 m³, and the total mass of the
boat when empty is 8560 kg.

a lake.
a. 171,500 kg
c. 193,200 kg
d. 184,250 kg
b. 176,900 kg
15. Determine how much load this can carry without sinking in
seawater with a specific gravity of 1.03.
a. 171,500 kg
c. 193,200 kg
b. 176,900 kg
d. 184,250 kg
