70% to passYour vessel is participating in the Voluntary Observing Ship Program, you are preparing WS Form B-80 as seen in illustration D041NG below. The dry bulb thermometer reads 54°F and the wet bulb thermometer reads 50°F. How would you encode the air temperature groups in the report?
A
054//, 047//
B
10122, 2008/
C
1054/, 2047/
D
1054/, 2050/
AI Explanation
The correct answer is B) 10122, 2008/. The air temperature groups are encoded as follows: - The dry bulb temperature of 54°F is encoded as 10122 (1st digit = 1 for 10s, 2nd & 3rd digits = 01 for 10, 4th digit = 2 for 2°F). - The wet bulb temperature of 50°F is encoded as 2008/ (1st digit = 2 for 20s, 2nd & 3rd digits = 00 for 0, 4th digit = 8 for 8°F, 5th digit = / to indicate the wet bulb). The other options are incorrect because: - A) and C) do not correctly encode the wet bulb temperature. - D) encodes the wet bulb temperature as 50°F instead of 2008/.
