Chapter 15: Problem 4

Why is it easier to float in the ocean than in fresh water?

Short Answer

Expert verified
It's easier to float in the ocean than in fresh water because the ocean water is denser due to the dissolved salts it contains. This increased density provides more buoyant force, helping objects to float more easily.

Step by step solution

01

Understanding Buoyancy

Buoyancy is a force exerted by a fluid that opposes the weight of an immersed object. In a column of fluid, pressure increases with depth due to the weight of the overlying fluid.
02

Comparison between Fresh Water and Salt Water

The primary difference between fresh water and salt water is the presence of dissolved salts in the latter, which increases the density of salt water.
03

Reason for Easier Floating in Ocean

With greater density, salt water exerts a greater buoyant force on the body than freshwater. This means that it is easier to float in the ocean than in a freshwater body because of the increased buoyant force.

Styrofoam's density is \(160 \mathrm{~kg} / \mathrm{m}^{3}\). What percent error is introduced by weighing a Styrofoam block in air (density \(1.2 \mathrm{~kg} / \mathrm{m}^{3}\) ), which exerts an upward buoyancy force, rather than in vacuum?

A fire hose \(10 \mathrm{~cm}\) in diameter delivers water at \(22 \mathrm{~kg} / \mathrm{s}\). The hose terminates in a \(2.1-\mathrm{cm}\)-diameter nozzle. What are the flow speeds (a) in the hose and (b) at the nozzle?

A typical mass flow rate for the Nile River is \(2.8 \times 10^{7} \mathrm{~kg} / \mathrm{s}\). Find (a) the volume flow rate and (b) the flow speed in a region where the river is \(1.8 \mathrm{~km}\) wide and averages \(8.2 \mathrm{~m}\) deep.

You're testifying in a drunk-driving case for which a blood alcohol measurement is unavailable. The accused weighs \(140 \mathrm{lb}\), and would be legally impaired after consuming \(36 \mathrm{oz}\) of beer. The accused was observed at a beach party where a keg with interior diameter \(40 \mathrm{~cm}\) was floating in the lake to keep it cool. After the accused's drinking stint, the keg floated \(1.2 \mathrm{~cm}\) higher than before. Beer's density is essentially that of water. Does your testimony help or hurt the accused's case?

At a hearing on a proposed wind farm, a wind-energy advocate says an installation of 900 turbines, with blade diameter \(110 \mathrm{~m}\), could displace a 1-GW nuclear power plant. You're asked if that's really possible. How do you answer, given an average wind speed of \(10 \mathrm{~m} / \mathrm{s}\) and a turbine power output that averages \(30 \%\) of the theoretical maximum?
