Consider schematic representation of tank initially and finally/At initial condition, tank is filled with air. Thus, air volume inside the tank is equal to internal volume of the tank.At final condition, assume volume of air is removed into the plastic bag. As per Buoyancy principle, lift occurs when buoyancy force is equal to the gravitational pull.Write expression for total buoyancy force needed.Here is empty tank, is mass of air, is density of air, and is total air volume.Substitute all known values.Tank :Evaluate mass density of tank material.Here is density of water.Substitute all known values.Consider expression for volume occupied by only tank metal material.Evaluate buoyancy force acting on partially filled tank.Write expression for buoyancy force acting on partially filled tank.Though tank is partially filled, volumed displaced by it is equal to volume of tank material and tank's internal volume. Thus, Substitute all known values.Plastic bag :Neglect the volume occupied by the plastic bag material. Thus, mass of plastic bag filled with air is equal to mass of air inside the plastic bag.Consider expression for buoyancy force acting on plastic bag.Thus, at final condition, the tank will lift when buoyancy force acting on partially filled tank and plastic bag is equal to gravitational pull of both partially filled tank and plastic bag.Equate the individual buoyancy forces to the total required buoyancy force.Substitute all known values.Evaluate mass of air inside plastic bag.Thus, volume occupied by the air inside plastic bag is and its mass is .(Note : From above result, it is clear that air volume inside plastic bag is more than air volume at initial condition. This is due to the fact that air expansion takes place when removed from tank into plastic bag.)

A scuba tank is dropped overboard and sinks to the ocean floor 20 ft below (T = 62 F). The composite metal (SG = 4.5) tank has a mass of 31.7 lbm when empty and has an internal volume of 0.355 ft3. The tank is currently filled with air to about 3000 psig. To retrieve the tank, you plan to dive down, open the valve, and let out air until the tank begins to float upward. Then, I realized that my plan to float the tank by letting out air wouldn't work. My second thought is to swim down, attach an empty plastic bag to the air valve, and release air from the tank into it. Will this work? If so what will be the volume of air in the bag when the tank just lifts off the ocean floor (ft3) and what will be the mass of air in the bag?

**Scenario: Retrieving a Sunken Scuba Tank**

A scuba tank is dropped overboard and sinks to the ocean floor 20 feet below (with a temperature of 62°F). The composite metal of the tank has a specific gravity (SG) of 4.5. The tank has a mass of 31.7 lbm when empty and an internal volume of 0.355 ft³. Currently, the tank is filled with air at approximately 3000 psig. To retrieve the tank, the plan is to dive down, open the valve, and release air until the tank begins to float upward.

Initially, the plan to float the tank by letting out air was deemed ineffective. As a second strategy, the idea is to swim down, attach an empty plastic bag to the air valve, and release air from the tank into it.

**Questions for Consideration:**
- Will this method work?
- If so, what will be the volume of air in the bag when the tank just lifts off the ocean floor (in ft³)?
- What will be the mass of the air in the bag?

You are about to ride a roller-coaster at Disney. The ride is a single-person ride with a drop of 25.0 meters and a plunger/piston system that makes the ride stop. There is a 250 kg water cylinder attached to the plunger/piston. The cart weighs about 75.0 kg and begins at the top of the circuit at a standstill. To get the total mass of the cart during the ride, you must add your weight (55KG) to the cart's overall weight. According to analysis, friction in the wheels and axles creates 2750 J of combined thermal and sound energy when the cart moves along the track. The bottom of the device's plunger/piston is designed to stop the cart at a max acceleration of 5.00 g's (49.0 m/s2). Question: Question #5: The plunger/piston compresses the water inside the cylinder, which is thenturned into thermal energy within the water. Determine the temperature change of the waterin the cylinder as it pulls the cart to a stop if the specific heat capacity of water is 4184J/kg°C (assuming 100 percent…
(Just Question a.) A water filled pipe has water flowing at v1= 5.90 m/s in a section of pipe where the diameter is d1= 20.2 cm and the pressure is known to be P1= 7.00×104 N/m2 above atmospheric pressure. If the pipe carries the water 3.5 meters up hill without any change in diameter, what is the new absolute pressure within the pipe? After flowing up the hill described above, the pipe narrows to 80% of its original radius, what will be the new water velocity (v2) in the pipe? What will be the absolute pressure (P3) in the smaller pipe? a. What is the volume flow rate through the smaller pipe?
The Super Soaker XP30 is a marvel of hydraulic dispersion weaponry. By pumping on the handle, you charge the chamber to high pressure. The pressure is maintained until you pull the trigger at which point the water (? = 1000 kg/m3) is released at high velocity.You have charged your pressure chamber to an absolute pressure of P1 = 697500 Pascals, much higher than today's outside air pressure of 101300 Pascals. The pressure chamber is location at a height of y1 = 0.103 meters above the exit point. The exit point has a small opening with radius r = 0.0033 meters.Determine all the following:The velocity at which the water exits the Super Soaker: v2 = m/sThe mass flow rate through the exit: kg/secThe volume flow rate through the exit: m3/secNOTE: You may treat the water chamber as a "tank" and approximate the water velocity there to be zero.

You are designing a hydraulic lift for an automobile garage. It will consist of two oil-filled cylindrical pipes of different diameters. A worker pushes down on a piston at one end (d = 25cm), raising the car on a platform at the other end (d=?). To handle a full range of jobs, you must be able to lift cars up to 3000 kg, plus the 700 kg platform on which they are parked. To avoid injury to your workers, the maximum amount of force a worker should need to exert is 100 N. What should be the diameter of the pipe under the platform? If the worker pushes down with a stroke 50 cm long, by how much will he raise the car at the other end?
