Pressure in a Fluid – year 9
/0 Comments/in Year 9 Physics Physics Year 9, Secondary/by JonathanWorksheet: Pressure in a Fluid (Year 9)
Lots of companies around Newcastle build machinery for the offshore industry – footings for wind turbines, robots to lay or inspect cables, and more. Testing machines designed to be used underwater isn’t just a case of dunking them in water. You also have to think about pressure. This worksheet takes students through concepts and calculations about pressure in a fluid, and introduces local engineering company Tyne Subsea, whose hyperbaric chambers are used to test underwater machinery.

Soil Machine Dynamics (SMD) design and manufacture subsea robotic machines. The deep sea floor is still one of the most unexplored, and inhospitable, places on Earth. No light, no warmth and high pressure all make it a challenging environment to work in. Why work under the sea? Well, every time you use the internet it’s likely that some of the information came through cables which are laid in a trench under the sea floor. Those trenches need to be dug and the cables need to be laid somehow. Or if you’ve seen off-shore windfarms, have you wondered how the electricity gets back to shore? More cables on the sea floor. It isn’t possible for people to lay these trenches themselves, so a robotic machine, also called a Remotely Operated Vehicle (ROV) is used to dig the trenches and lay the cables. The engineering that goes into the development of ROVs is staggering as they need to be both robust enough to survive in such a harsh environment as the bottom of the sea, and easily controllable. This video shows how an ROV digs a trench and lays a cable in it. The language is aimed at people looking to buy one of the machines so uses a bit of jargon, but the animation does help to show how the machine works.Who Are They?
Careers
To design, develop and make ROVs requires a lot of different STEM, and non-STEM, based roles.
Among the different roles at SMD are:
- Mechanical Engineers
- Electrical and Electronic Engineers
- Software Engineers
- Hydraulic design engineers
- Sales Engineers
- Health & Safety Advisers
- Quality Systems Engineer
- PR and Communications Officers
- Test Technicians and Assistants
Although based in the North East, SMD is a global company, so there could be opportunities to travel.
