1. Costs and frequency of change.
2. The most important ‘non-functional’ requirements. Different systems have different priorities for non-functional requirements.
3. The software lifetime and delivery schedule.
Explanation:
The process of requirement gathering is required in both generic and customized software.
• A document to define the development process is required in all type of software application.
• Updating is required in each type of software. For doing so, new version of each type of software is released.
• Maintenance is an important part of software development. It is required in each type of application development.
• Software has some minimum requirements to execute. So, platform dependability is considered in all software development.
Answer:
Explanation:
Reynolds number:
Reynolds number describe the type of flow.If Reynolds number is too high then flow is called turbulent flow and Reynolds is low then flow is called laminar flow .
Reynolds number is a dimensionless number.Reynolds number given is the ratio of inertia force to the viscous force.
For plate can be given as
Where ρ is the density of fluid , v is the average velocity of fluid and μ is the dynamic viscosity of fluid.
Flow on plate is a external flow .The values of Reynolds number for different flow given as
