1. Design a small, single-cylinder Stirling or Ericsson cycle external combustion engine that can be used to demonstrate the operation of this type of engine in the classroom. Choose a convenient fuel such as alcohol. Provide detailed working drawings and a thermodynamic analysis.
2. Design a Brayton cycle power system to propel a small drone aircraft that will be used for military target practice. The fueled drone must weigh less than 500. kg, and since these aircraft are not reusable, they must be produced at minimum cost.
Determine or specify the air mass flow rate, pressure ratio, compressor and turbine isentropic efficiencies, turbine inlet temperature, thrust, thrust to weight ratio, exhaust temperature, and hot ASC thermal efficiency. A computer program will help you carry out parametric studies of the variables involved.
Calculate the intensity distribution
A wildlife biologist tracks an elk over flat terrain by following the emissions from a radio collar worn by the animal. If the elk travels 3.0km at an angle of 30 degrees East of North, followed by 2.0km at 40degrees West of North, and finally a 4..
An object is located a distance do = 5.8 cm in front of a concave mirror with a radius of curvature r = 22.2 cm. Write an expression for the image distance
The Space Shuttle travels at a speed of about 7.75E+3 m/s. The blink of an astronaut's eye lasts about 112 ms. How many football fields (length = 91.4 m) does the Shuttle cover in the blink of an eye
A box of 20 kg is pushed up a 15 degree frictionless incline plane at a uniform speed. The applied force on the box is directed at a 20 degree angle from the horizontal. Draw a force diagram for the box.
What is the equilibrium concentration of electrons and holes in an n-type silicon at T=21.2°C (ni = 1.0x1010cm-3) in which NDD=4x1010cm-3 and are all ionized, and NAA=0? How much error is introduced if the intrinsic electron is neglected?
In the circuit shown, R1= 800 ohms, R2= 500 ohms, R3= 200 ohms, and V=9V. Find the equivalent resistance of the whole circuit
A typical red blood cell has a mass of 3.0 x 10-16 kilogram. Evaluate what is the diameter of the centrifuge
a golf ball rolls of a cliff with an inital speed of 13.0 m/s. theball falls a vertical distance of 18.8 m into a lake below. Ittakes 1.45 s. What is the speed of the ball just before it hits the water
A mass hanging from a spring can oscillate in the vertical direction or can swing as a pendulum of small amplitude, however not both at the same time. Which one is longer, the period of the vertical oscillations or the period of the horizontal swings..
Assume that electrons are the charge carriers and the conduction electron density is 2.35 x 10^23/ m^3. then calculate the electron drift speed in the wire.
Two resistors, 42.0 ohm and 72.0 ohm are connected in parallel. The current through the second resistor is 4.30 Amp. Find what is the current in the first resistor
