What is single bit error correction? The process or method of correcting single bit errors is called “single bit error correction”. The method of detecting and correcting burst errors in the data sequence is called “Burst error correction”. What are error correcting codes in communication? In computing, telecommunication, information theory, and coding theory, an error […]
What is the effect of water jet on vanes?
What is the effect of water jet on vanes? Turbines rotate due to force exerted by one or more water jets that are directed tangentially onto the turbine’s vanes or buckets. The impact of the water on the vanes generates a torque on the wheel, causing it to rotate and to generate electricity. When a […]
When a ray of light reflects off a surface the angle of incidence is equal to the angle of reflection?
When a ray of light reflects off a surface the angle of incidence is equal to the angle of reflection? Figure 1. The law of reflection states that the angle of reflection equals the angle of incidence—θr = θi. The angles are measured relative to the perpendicular to the surface at the point where the […]
How is permeability of soil calculated?
How is permeability of soil calculated? The coefficient of permeability can be calculated using the pressure measurements and volume of the permeated water during the set time interval, as well as the height and cross-sectional area of the soil sample. To ensure accurate results, repeat the test three or more times and find an average […]

How do helicopters hover?
How do helicopters hover? As the propeller blades of a helicopter slice through the air, it creates a strong wind. The wind moves downward pushing the helicopter. The air beneath the blades thus, has greater pressure than the air above them. This is what enables a helicopter to go straight up or down or hover […]
What is meant by thermal stratification?
What is meant by thermal stratification? Thermal stratification occurs when two types of steam with different temperatures come into contact. Their temperature difference causes the colder and heavier water to settle at the bottom of the pipe while allowing the warmer and lighter water to float over the colder water. What causes stratification? Stratification occurs […]
How do you read tap and die sizes?
How do you read tap and die sizes? Thus, a tap or die marked 1/4-20 NC cuts threads for a 1/4-inch-diameter screw or bolt with 20 coarse threads per inch. Taps and dies with diameters less than 1/4-inch are numbered according to the wire gauge sizes of machine screws. For example, a die marked 10-32 […]
How do you calculate the angle of a wheelchair ramp?
How do you calculate the angle of a wheelchair ramp? For commercial use when somebody is sitting in the wheelchair or scooter while it climbs the ramp, ADA recommends a 1:12 slope, which means that every 1″ of vertical rise requires at least 1′ (12″) of ramp length (5 degrees of incline). Example: A 24″ […]
