Question

A nice way to move a heavy underwater rock in the ocean (if you ever need to do that) is to attach the rock to an empty drum using a rope during low tide. When high tide comes in, the buoyant force will lift the rock if the drum is sufficiently big (see below). The density of sea water is approximated as rho water ​ =1.0⋅10 3 kg/m 3 and the density of the rock is rho rock =5.0⋅10 3 kg/m 3 . Neglect the mass of the empty drum throughout this problem.(a) Determine the mass of the heaviest rock that can be lifted by a drum with radius R=0.35 m and length L=1.2 m. Assume the rock lies loose on the ocean floor. (b) While lifting a rock close to that weight, there is unfortunately a leak in the very bottom of the drum. The hole has a radius of r=0.0025 m . Determine the initial volume flow rate of water into the drum.

Answer 1

Determine the mass of the heaviest rock that can be lifted by a drum with a radius R=0.35m and length L=1.2m. Assume the rock lies loose on the ocean floor.

While lifting a rock close to that weight, there is, unfortunately, a leak in the very bottom of the drum. The hole has a radius of $r$=0.025m. Determine the initial volume flow rate of water into the drum.

ρ water =1.0 ⋅ $10^3$kg/$m^3$

and the density of the rock is

ρ rock =5.0⋅10 $10^{3}$kg/$m^3$

. forget about the mass of the empty drum at some point in this trouble. (a) decide the mass of the heaviest rock that can be lifted by using a drum with a radius

R=0.35 m

and length

L=1.2 m

Assume the rock lies loose on the ocean floor. (b) at the same time as lifting a rock close to that weight, there is lamentably a leak inside the very backside of the drum. The hole has a radius of

r=0.0025 m
