Complete question:
An airplane is cruising at a velocity of 800 km/h in air whose density is 0.526 kg/m³ . The airplane has a wing planform area of 90 m² . The lift and drag coefficients on cruising conditions are estimated to be 2.0 and 0.06, respectively. The power that needs to be supplied to provide enough trust to overcome wing drag is
Answer:
The power that needs to be supplied to provide enough trust to overcome wing drag is 15,600 kW.
(C) 15,600 kW
Explanation:
Given;
velocity of the airplane, v = 800 km/h = 222.22 m/s
density of air, ρ = 0.526 kg/m³
wing planform area, A = 90 m²
lift coefficients, CL = 2.0
drag coefficients, CD = 0.06
Power supplied = FD* V
This is approximately 15,600 kW.
Therefore, The power that needs to be supplied to provide enough trust to overcome wing drag is 15,600 kW.
The correct option is C
Answer:
By how it impacts our goals and the environment probably. Sorry if i'm wrong :(
Engineering is about building things, learning how to build things and it being fun
Answer:
Design of Experiment also known as DoE is a systematic methodology to understand how any process or parameters of any product affects the response variables like physical properties or performance of any product, etc. It serves the purpose of making the job easier.
It is technique to generate valuable information required with minimum experimentation with the use of these:
- Statistical methodology
- Mathematical analysis to predict the output within the limits of experiments at any point.
- Experimental extremities
Process Optimization:
It includes the following:
- Product prototype should be used in designing
- Optimization of significant value adding activities
- Detection and minimization of error
- Strong built concept for the design
- Testing and validation of the process for further improvement in efficiency
- Time, quality, environmental, manufacting and overall cost, safety and operational constraints should be duly noted.
Answer: efficient communication between engineers and teams
Explanation: Concurrent engineering concept or design is a strategy where all the tasks involved in product development are done in parallel. It is an approach used in product development in which all functions are integrated to reduce the time required to bring a new product to market.
One of the major challenges engineering managers face here is effective and efficient communication. To start with, every member of the team must know the design goals/objectives and must be aware of the interrelationships between all aspects of the design process, therefore there is need for superior communication between all sections of the company.
There are now service providers who not only train people on how to perform concurrent design effectively, but also provide the necessary tools to enhance communication between the team members.
