What does a low drag coefficient mean? It is used in the drag equation in which a lower drag coefficient indicates the object will have less aerodynamic or hydrodynamic drag. The drag coefficient is always associated with a particular surface area. Is a lower drag coefficient better? Aerodynamic drag increases with the square of speed; […]

Other matrix materials can be used and composites may also contain fillers or nano-materials such as graphene. Whats is composite? In math, composite numbers can be defined as […]
What is the lifetime of a typical sunspot?
What is the lifetime of a typical sunspot? around eleven years What is the cause of sunspots? Sunspots are magnetic in nature. They are the places (“active regions”) where the Sun’s magnetic field rises up from below the Sun’s surface and those magnetic regions poke through. Sunspots are formed continuously as the Sun’s magnetic field […]
How are turbine blades attached to turbine discs?
How are turbine blades attached to turbine discs? A series of grooves or notches, conforming to the blade root design, are broached in the rim of the disk. These grooves allow attachment of the turbine blades to the disk; at the same time, space is provided by the notches for thermal expansion of the disk. […]
What is the best source of energy for the country?
What is the best source of energy for the country? Nuclear Has The Highest Capacity Factor As you can see, nuclear energy has by far the highest capacity factor of any other energy source. This basically means nuclear power plants are producing maximum power more than 93% of the time during the year. What is […]

What is forced convection how does it differ from natural convection?
What is forced convection how does it differ from natural convection? In natural convection, any fluid motion is caused by natural means such as the buoyancy effect, i.e. the rise of warmer fluid and fall the cooler fluid. Whereas in forced convection, the fluid is forced to flow over a surface or in a tube […]
What are the theorems of Pappus and Guldinus used for?
What are the theorems of Pappus and Guldinus used for? Explanation: The theorem is used to find the surface area and the volume of the revolving body. It is just the product of the area, length of generated curve and the perpendicular distance from axis. The distance being the distance travelled by the centroid. What […]
