Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.

### Transcription of Educational Content

**Scenario: Winch Operation in Construction**

An electric winch is being used to help construct your facility. The winch operates at 71% efficiency with an input voltage of 120 volts $[V]$. When the winch lifts an object to a height of 7 meters $[m]$ in 25 seconds $[s]$, a current of 21 amperes $[A]$ is required.

**Question:**
What is the approximate weight of the object the winch lifted in units of newtons $[N]$?

- Click the icon to view the table of common derived units in the SI system.

**Answer:**
The weight is $6300$ $N$. (Round your answer to a whole number.)

⦁ “God himself could not sink this ship” This is an advertisement for the Titanic, produced in the early 1900s. However, after colliding with an iceberg at dawn on April 15, 1912, two rivers were formed, and out of the 2,200 people on board, 1,500 people, including the captain, sank with the ship. According to a later investigation, the “temperature change theory” (DBTT theory) was the most promising cause of the sinking. Give a brief guess of the cause of the ship's sinking in relation to temperature.
