What is the amount of force that a braking system requires the driver to apply to stop a vehicle? On a hydraulic brake system, the driver generates force by pressing on the brake pedal. The force is then amplified by the pedal, booster and master cylinder. The driver will modulate the pressure on the pedal […]
Does sewage go into Lake Michigan?
Does sewage go into Lake Michigan? In 2018, the agency overseeing Milwaukee’s system, which serves 1.1 million people and 28 communities, saw six combined sewer overflows — the most events since 1999. Those overflows sent 1.2 billion gallons of stormwater and untreated sewage into rivers, canals and a stream that drain into Lake Michigan. Is […]
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 […]
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 […]
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 […]
