After completing your physics class, you are hired to help design a cigar lounge in a nightclub. The ventilation system is critical to this design, as it must circulate all the air in the room every 27 min to filter and purify it, respecting national health regulations. The ventilation ducts you will use have a square cross-section. If the lounge has a volume of 184 m3, and the fans pushing the air give you an airspeed of 3.9 m/s inside the ducts, what must be the minimum length of one side of the square duct? Assume that air can be treated as an incompressible fluid. Give your answer in metres

An aquarium 9 m long, 1 m wide, and 1 m deep is half-filled with water. Find the work needed to pump the water out of the aquarium. (Use 9.8 m/s2 for g and the fact that the density of water is 1000 kg/m3.)
A 5 kg bag of sand is poured into a funnel and allowed to flow out the bottom of the funnel and onto a scale that is 2.8 m below, where the sand collects. If it takes 11 seconds for all of the sand to flow out of the funnel, what does the scale read 8 seconds after the sand begins collecting? State your answer to the nearest 0.1 N. (Let g= 10 m/s2)

Your answer is partially correct. Crossing a River. You and your team come to a slow flowing river that you need to cross. The nearest bridge is 20 miles to the north, too dangerous and too far to trek with your group. You explore the area down river and discover an abandoned shed with a stash of 55-gallon drums (all empty and weighing 35.0 lb each) and a stack of 10-foot planks: you will build a raft. The six members of your team have a combined weight of 1015 pounds (assuming everyone was truthful). You also have a four-wheeler (all-terrain vehicle), which weighs 460 lb, and other gear, which adds another 325 lb. Your simple raft design is as follows: platform of planks with barrels strapped to the bottom. You estimate that the planks weigh about 49.0 lb each, and you will need 20 of them to make a platform that can accommodate everything for the one-way trip. You measure the dimensions of the cylindrical drums and find they have diameter D = 23.0 inches and height h = 34.5 inches…
A balloon filled with helium gas has an average density of ρb = 0.31 kg/m3. The density of the air is about ρa = 1.23 kg/m3. The volume of the balloon is Vb = 0.075 m3. The balloon is floating upward with acceleration a. Calculate the numerical value of F in N.
A car with two passengers and fuel weighs 1000 kg. It has wings with an area of 16 m^2 that are designed such that air moving over them must travel 1.05 times as far as air moving under them. How fast must this plane be moving so that wings generate enough lift to offset the plane's weight? The wings are thick. Please give answer in m/s
You are working as an assistant to a landscape architect, who is planning an artificial waterfall in a city park. Water flowing at 1.88 m/s will leave the end of a horizontal channel at the top of a vertical wall h = 3.10 m high, and from there it will fall into a pool (see the figure below). (a) The architect has asked you to determine if the space behind the waterfall will be wide enough for a pedestrian walkway. (Enter the maximum width, in meters, of a walkway behind the waterfall.) m (b) To sell her plan to the city council, the architect wants to build a model to standard scale, which is one-twelfth actual size. She asks you to design and build the model, with the important question being: how fast (in m/s) should the water flow in the channel in the model? m/s
A cylinderis fitted with a piston beneath which is a spring, as in the attachment. The cylinder is open to the air at the top. The sprink constant is 4300 N/m. The piston has negligible mass and a radius of 0.032. When the air beneath the piston is completely pumped out, how much does the atmospheric pressure cause the spring to compress? How much work does the atmospheric pressure do in compressing the spring.
