Ummmmmmm do u need help with anything ✌?
Answer:
763.94Wh
Explanation:
If the load is 120 watts running for 4 hours per night, the energy consumed is
120*4 =480 Wh
So, the energy gathered by the PV array is
E=480/(77%*96%*85%)=763.94Wh
Answer:
- Fins should be attached outside the tube
- Fins can be attached on both sides when convection coefficient of air inside the tube is equal to the convection coefficient of atmospheric air outside the tube
Explanation:
The main function of the fins that are to be added is to ensure the speedy transfer of heat from the Hot air.
The fins should be attached outside the tube because the convection coefficient of air is higher inside the tube than the convection coefficient of the outside air ( atmospheric air ), BUT
When convection coefficient of air inside the tube is equal to the atmospheric air outside the tube, it is recommended that the fins can be added on both sides of the tube ( i.e. in and outside the tube )
Projects that don't have human factors involved are:
- The Use of Artificial Intelligence to Power Road Construction Robots;
- End to End robotic Automobile production line.
Other projects that require human factors are;
- Traditional road construction projects;
- Traditional building construction projects.
<h3>What are the human factors for Road Construction?</h3>
The role of human factors includes but is not limited to:
- Operation of Heavy-Duty Vehicles
- Human Resources (taking care of people)
- Finance operations (Finance and Accounting) etc.
At construction sites, excavation is one of the roles of humans. Another instance is injuries, compensation, etc is the work of the Human Resources Officer.
Human factors include environmental, organizational, and job elements, as well as human and individual qualities that influence workplace behavior and can have an impact on health and safety.
Human-factors engineering has been applied to simple equipment such as highway signs, telephone sets, hand tools, and stoves, as well as a wide range of contemporary, sophisticated complexes such as data systems, automated warehouses, and factories. robots, and space vehicles.
