A) 246 lbs
B) 79 lbs
C) 193 lbs
D) 107 lbs
This fluids study problems explains how to calculate volume, specific gravity and weight of an object when placed in water and crude oil.
Calculating buoyant force of water
Calculating the volume of water displaced
The volume is 3.77 cubic feet
Choice A is correct
Calculating specific gravity of the equipment
The specific gravity of the equipment is 1.28
Choice C is correct
Convert API to SG
Calculate the weight of oil displaced
Calculate the weight of the equipment in oil
The weight of the equipment in oil is 107 lbs
Choice D is correct
