How is refrigerant cooled? As refrigerant absorbs heat from indoor air, it transitions from a low-pressure gas to a high-pressure liquid. Air conditioning components send the refrigerant outside where a fan blows hot air over the coils and exhausts it to the exterior. The refrigerant then cools down and turns back into a low-pressure gas. […]
What is the safety measurement system?
What is the safety measurement system? The Safety Measurement System (SMS), a branch of the Federal Motor Carrier Safety Administration (FMCSA), identifies and intervenes with drivers who have demonstrated unsafe driving behavior. It uses seven distinct categories, known as BASICs, to identify, categorize, and rank drivers to prioritize for intervention. Who is affected by the […]
Why are most aircraft painted white?
Why are most aircraft painted white? Painting an aircraft white helps to reflect the sunlight and minimize the amount of energy needed to keep the plane comfortable. Modern planes that are made from composite materials need even more protection from the sun as they can be damaged by UV radiation, which is another reason why […]
What is being emitted in an LED?
What is being emitted in an LED? LED is an abbreviation of Light Emission Diode, and is a device which emits light by flowing a current to the p-n junction like a semiconductor laser (LD). It emits various wavelength lights in the ultraviolet, visible and infrared regions, corresponding to its band gap energy. Why LED […]
Does laminar or turbulent flow have more shear stress?
Does laminar or turbulent flow have more shear stress? Hence, the shear stress is larger in the turbulent flow than that in the laminar flow. Which boundary layer has more energy laminar or turbulent? A turbulent flow boundary layer has more energy than a laminar flow layer, so it can withstand an adverse pressure gradient […]
What type of voltage does a thermocouple produce?
What type of voltage does a thermocouple produce? The voltage output ranges from about -10 to 77 mV (depending on the thermocouple type and measurement temperature). The correlation of temperature versus voltage establishes a relationship that is unique to the various thermocouple types. Does a thermocouple produce AC or DC voltage? Being the thermocouple voltage […]
How do you calculate gear design?
What does it mean to have freedom of expression?
What does it mean to have freedom of expression? Freedom of expression refers to the ability of an individual or group of individuals to express their beliefs, thoughts, ideas, and emotions about different issues free from government censorship. Are there limits to freedom of expression? Freedom of speech and expression, therefore, may not be recognized […]
How is multiple cropping different from mixed farming?
How is multiple cropping different from mixed farming? In mixed cropping or mixed farming, two independent crops are mixed together and grown in an area, whereas the intercropping is a multiple cropping techniques where two or more crops are grown in proximity. … What is multi cropping? In agriculture, multiple cropping or multicropping is the […]
What determines the speed of an AC induction motor quizlet?
What determines the speed of an AC induction motor quizlet? Ac induction motor speed is determined by the current frequency and the number of. This type of ac motor is characterized by low starting torque and is suitable for light applications such as a refrigerator evap motors. What are the two principal parts of an […]
