What is external forced convection how does it differ from internal forced convection can a heat transfer system involve both internal and external convection at the same time give an example? If the fluid is forced to flow over a surface, it is called external forced convection. If it is forced to flow in a […]
How can you determine the specific heat of a metal using a calorimeter?
How can you determine the specific heat of a metal using a calorimeter? Place the metal piece into the water of the calorimeter and measure the highest temperature reached by the water. This is the final temperature of both the metal and the water. The energy change of water is calculated by rearranging the specific […]
When the angle between surface tension with the liquid θ is greater than 90 degree the liquid becomes?
When the angle between surface tension with the liquid θ is greater than 90 degree the liquid becomes? If θ is obtuse, i.e; θ >90°, then liquid meniscus will be convex upwards. If angle of contact is acute angle, i.e; θ <90°, then liquid will wet the surface. When there is a capillary depression What […]
How do you test a 3 phase motor with a Megger?
How do you test a 3 phase motor with a Megger? Turn off the power supply to the motor, usually accomplished by switching the circuit breaker. Place one megger probe to the any mounting bolt on the breaker box to test for grounding continuity, then touch the other probe to a motor terminal. Crank the […]
How do you find the critical buckling load?
What is disturbance control system?
What is disturbance control system? A disturbance signal is commonly found in control systems. Disturbance signals represent unwanted inputs which affect the control-system’s output, and result in an increase of the system error. What is tracking error control systems? A tracking control system is designed to have a low steady-state error in response to a […]
How do you reverse engineer a product?
How do you reverse engineer a product? THE REVERSE ENGINEERING PROCESS. To reverse engineer a physical product, an organization will typically acquire an example of the product in question and take it apart to examine its internal mechanisms. This way, engineers can unveil information about the original design and construction of the product. How is […]
What happens when you put ice in a warm drink?
What are the requirements to be a robotic engineer?
What are the requirements to be a robotic engineer? Though a bachelor’s degree is thought to be the bare minimum required level of education for robotics engineers, many employers will now only consider job applicants who have earned at least a master’s degree, such as a Master of Science in Robotics. What type of education […]
What does the FTC Act prohibit?
