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 […]

How does participating in extracurricular activities help students?

What are the benefits of extra curricular activities? 5 Important Benefits of Extracurricular […]

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 […]

What time zone are flights shown in? Airline departure and arrival times are always given in terms of the local time zone – that is, the time zone at the airport in question for each segment of the trip. So if you’re flying from the West Coast of the United States to the East Coast, […]

What is the formula for a random number generator? This generator produces a series of pseudorandom numbers. Given an initial seed X0 and integer parameters a as the multiplier, b as the increment, and m as the modulus, the generator is defined by the linear relation: Xn ≡ (aXn-1 + b)mod m. Or using more […]

What is the role of planning engineer? Planning Engineers help engineering teams deliver projects on schedule. They develop strategies, determine material and labor costs, monitor crew performance, ensure health and safety regulations are obeyed, and that communications channels are open. Which task best fits the role of a design engineer? Explanation: Design engineers study, research […]

Why do cars need to be aerodynamic? The main concerns of automotive aerodynamics are reducing drag, reducing wind noise, and preventing undesired lift forces at high speeds. For some classes of racing vehicles, it may also be important to produce desirable downwards aerodynamic forces to improve traction and thus cornering abilities. What is the purpose […]

What is the overall effect of using a chronological text structure? Readers can follow the progress of events surrounding an important moment. Chronological order helps readers understand the order in which things happened, from the first event or detail to the last. This helps give an accurate picture to how the event unfolded and what […]
