At the AQWA facility in Hillarys, patrons view the marine life while walking through a tunnel formed by a semi-cylinder glass wall. The aquarium contains sea water (Specific Gravity 1.025), and the highest point of the glass wall lies 8 metres below the water surface. If a section of the glass wall is 2.5 metres in radius and 10 metres long, determine the magnitude and direction of the force exerted on the section.

（This is Chemical Engineering question (about Hydrostatics/Shell Momentum Balances), please help me to solve it, thanks)

Expert Solution

vol of water above glass wall = cross-section of wall * height of water on class wall

= Pie * r^2 * h

=ss/7 * (2.5)^2 * 8 = 157.142

Weight of water above glass wall = vol * specific gravity * g

= 157.142 * 1.025 *9.8 = 161.07 * 9.8 = 1578.486 N

= magnitude of force ofwater above glass wall on glass wall

Force will act in downward direction on glass wall .

A water tunnel is mined through a mudstone rock mass at a depth of 200 m. The rock mass consists of three fracture sets. One set is the bedding planes; these are highly weathered, slightly rough surfaces and are continuous with an orientation of 180/10. The first number is the dip direction which is an azimuth measure from the North. Dip direction is measured 90° clockwise from the strike. The second number is the dip. The second set of fractures...

Many exercise apps record both the time and the distance a user covers while walking, running, biking, or swimming. Some users of the apps want to know their average pace in minutes and seconds per mile, while others want to know their average speed in miles per hour. In many cases, we are interested in projected time over a specific distance. For example, if I run 6.3 miles in 53 minutes and 30 seconds, my average pace is 8 minutes...
