5. The mission profile for a 4-engine jet aircraft consists of the following segments: engine start and warm-up, taxi, take-off, climb to an altitude of 20000 ft followed by a cruise distance of R₁ nm at 350 kts, climb to an altitude of 35000 ft, followed by a cruise distance of R2 nm at 450 kts descent to 10000ft followed by one hour loiter and flight to an alternate airport at R3 nm distance both at 250 kts, descent to landing approach condition followed by the final landing, taxi and shutdown. The total distance during the cruise segments and flight to an alternate airport is restricted to a maximum of 5100 nm. Based on the existing manufacturers' data you may use the information provided in Table QA-1.

24 Problem: Mathematics in Wind Energy Production Wind power is defined as the use of air flow through wind turbines to provide the mechanical force to generate electricity. Wind power is an alternative to burning fossil fuels, and is renewable and produces no greenhouse gas emissions during operation. Modern horizontal-axis wind turbines often use three blades. Theoretically, the maximum power P (unit: watts) that a three-blade wind turbine can extract from the wind power can be calculated as: Blade 1. %3D (Equation 1) dɔzayd² = d where p is the air density (kg/m'), A is the sweep area of the turbine (m²) and can be calculated from the length of the turbine blades, and v is the wind speed (m/s). C, is the power coefficient that is unique to each turbine type. This coefficient represents the amount of kinetic energy from the wind that is captured by the turbine. From the Betz's limit law we know that the best power conversion possible is Cp,max = 0.59. Part 1 Given the following data:…

An aerospace engineer is volunteering as a mentor for a high school team competing in a national contest to build a robot that straightens boxes. The plan was to help the students on weekends for at most eight to ten hours. As the national competition nears, the robot’s motor overheats, and the engine burns out. He wants to help the dispirited students and believes his mentoring commitment requires he do more. But doing so would involve additional evening work that could potentially harm his work, if not his family.

answer a & b. Please show all your work!!

Answer question 2 based on the results of question 1. You have a natural gas furnace in your home that used 78,500 cubic feet of natural gas for heating last winter. Your neighbor has a furnace that burns heating oil, and used 516 gallons of heating oil last winter. You can convert the natural gas and heating oil consumption data into Btu to determine which home used more energy for heating. Natural gas BTU:  1,028 Btu per cubic foot Oil BTU: 138,590 Btu per gallon   Natural Gas BTU= 80698000 Btu Oil BTU                = 71512440 Btu   The home that used a natural gas furnace used more energy for heating. 2. You need a new furnace for your home, and you are comparing systems that use natural gas and heating oil. One factor to consider is the cost of fuel. You can compare the price of the fuels on an equal basis by dividing the price per unit of the fuels by the Btu content per unit of the fuels to get a price per million Btu. Assume Natural gas price = $10.50 per thousand cubic…

Task3

Part 1: Do the Analysis of the Ocean Thermal Gradient Power Plant shown below. Your Analysis will be easier to do in EES but it is up to you. Your EES program must be well documented and documentation in your code should reference system sketches. (The cycle and individual components) These sketches are done on attached engineering or typing paper, unless you are able to draw them in EES. You must validate your results with hand calculations on engineering paper that invoke the 1 and 2 Law from the perspective of the entire cycle, not the individual components. Of course, a system sketch is required. nd 1. An ocean thermal gradient power plant using a simple non-ideal Rankine Cycle operates with a peak boiler temperature of 70 °F and a condenser temperature of 40 °F. The warm surface water of the ocean is supplying the thermal energy to the boiler. Assume a high source temperature of 80 °F. The cooler water deeper in the ocean is the sink for heat rejection at the condenser. Assume a…
