Explanation:
CAD (computer-aided design) software is used by architects, engineers, drafters, artists, and others to create precision drawings or technical illustrations. CAD software can be used to create two-dimensional (2-D) drawings or three-dimensional (3-D) models
Answer:
Globalized economy.
Explanation:
The world economy is a global economic system made up of economies of countries that are more or less interconnected. One of the key words in the world economy is globalization, which means that national economies are so closely interlinked that events in one country usually affect the economies of other countries. Globalization has become particularly dominant over the last century. More and more trade is taking place between different countries, and restrictions on this have been significantly reduced. The result is a global economic phenomenon. People can sell goods and services in markets around the world, and consumers can choose from a much wider range of goods and services. It no longer has to be limited to what is offered in one's own country.
Answer and Explanation:
The heat engine are used for converting the heat energy into mechanical energy .When heat energy is converted into mechanical energy then this mechanical energy are used to do the useful work. Heat engine working based on the three process that are head addition , expansion and heat rejection.
Answer:
(a) The area of the duct exit is 1.67 m²
(b) The air pressure at the exit is 1.195 x 10⁵ N/m²
Explanation:
Given;
inlet area, A₁ = 5 m²
inlet velocity, V₁ = 10 m/s
exit velocity, V₂ = 30 m/s
(a) The area of the duct exit is determined by applying continuity equation;
A₁V₁ = A₂V₂
Where;
A₂ is the area of the duct exit
A₂ = (A₁V₁) / (V₂)
A₂ = (5 x 10) / (30)
A₂ = 1.67 m²
(b) Apply Bernoulli’s equation to determine the pressure at the exit;
Density of air at 300k = 1.177 kg/m³
Therefore, the air pressure at the exit is 1.195 x 10⁵ N/m²
