A prototype torpedo 6m long travels at 35 knots well
below the ocean surface at 20°C. A model is to be tested in a wind
tunnel 15°C air. What should the velocity, in m/s, of the model be
avoid compression effects?
The face of a dam is vertical to a depth of 6m below the water
surface and then slopes at an angle of 30◦ to the vertical. If the
depth of the water is 15m, specify completely the resultant force
per meter run acting on the face of the dam.
A proposed Ocean Thermal Energy Conversion (OTEC) plant draws
heat from the ocean surface at 22°C and rejects heat to the water
near the ocean bed at 4°C. What is the highest thermal efficiency
the plant could achieve? [4] (b) Consider a system undergoing an
adiabatic process from a fixed state 1 to a fixed state 2. Use the
Second Law of Thermodynamics to prove that the maximum work is done
by the system if the process is reversible. [6]...
A
scuba diver 40ft below the ocean surface inhales 50.0 mL of
compressed air from a scuba tank at a pressure of 3.50 atm and a
temperature of 6 degrees celsius.
Part A: What is the pressure of the air, in atm, in the lungs
when the gas expands to 150.0 mL at a body temperature of 37
degrees celsius, and the amount of gas remains constant?
A suba diver 60ft below the ocean surface inhales 50.0mL of
compressed air at 3.00 atm and 241K from a scuba tank. What is the
pressure of the air at 37C in the lungs where it expands to
150.mL?
The Mariana trench is located in the Pacific Ocean at a depth of about 11 000 m below the surface of the water. The density of seawater is 1025 kg/m^3. If an underwater vehicle were to explore such a depth, what force would the water exert on the vehicle's observation window (radius = 0.254 m)? For comparison, determine the weight of a jetliner whose mass is 1.17 times 10^5 kg.

Prototype your functions above "main" and define them below
"main";
Write a program that uses two identical arrays of at least 20
integers. It should call a function that uses the bubble sort
algorithm to sort one of the arrays in ascending order. The
function should keep count of the number of exchanges it makes. The
program then should call a function that uses the selection sort
algorithm to sort the other arrays. It should also keep count...

Water at a flow rate of 20,000 kg/h will be heated from 20°C to
35°C by hot water at 140°C. A 15°C hot water temperature drop is
allowed. A number of 3.5 m hairpins of 3 in. (ID = 0.0779 m) by 2
in. (ID = 0.0525 m, OD = 0.0603 m) counter flow double-pipe heat
exchangers with annuli and pipes, each connected in series, will be
used. Hot water flows through the inner tube. Fouling factors are:
