Why are water towers elevated? The primary function of water towers is to pressurize water for distribution. Elevating the water high above the pipes that distribute it throughout the surrounding building or community ensures that hydrostatic pressure, driven by gravity, forces the water down and through the system. Where do cities put their water towers? […]
What variables affect the efficiency of a heat engine?
What variables affect the efficiency of a heat engine? The thermal efficiency of a heat engine is expressed as a product of the Carnot efficiency, the external irreversibility factor and the internal irreversibility factor, by which the three factors that affect the thermal efficiency can be clearly distinguished, and the influences of the external and […]
How do you identify an antecedent?
What is ferrous alloy?
What is ferrous alloy? Ferrous alloys or metals are metals that consist mostly of iron (Fe). Steel is an iron-based alloy containing typically less than 1% carbon, where iron frequently contains 2% or more carbon. Is brass an alloy? Brass, alloy of copper and zinc, of historical and enduring importance because of its hardness and […]
How a signal can be represented in time domain or frequency domain?
How a signal can be represented in time domain or frequency domain? Put simply, a time-domain graph shows how a signal changes over time, whereas a frequency-domain graph shows how much of the signal lies within each given frequency band over a range of frequencies. The “spectrum” of frequency components is the frequency-domain representation of […]
What page replacement algorithm has minimum number of page faults?
What page replacement algorithm has minimum number of page faults? MIN (minimum) or OPT (optimal) : Belady’s optimal algorithm for the minimum number of page faults. replace the page that will be referenced furthest in the future or not at all. problem: we cannot implement it, because we cannot predict the future. Why page replacement […]
How do you make a traffic light system?
How do you make a traffic light system? Participants in the Design of Traffic Light System by using State Design Pattern ITrafficLight- It will define the methods to change the state and report state. ConcreteState- It will be an implementation of ITrafficLight Interface. TrafficLight- It will behave as a context for the traffic light or […]
What is the difference between 1018 and 4140 steel?
How does diffusion coefficient change with temperature?
How does diffusion coefficient change with temperature? We note also that the diffusion coefficient increases strongly with the temperature of contact. The coefficient of diffusion increases gradually as the temperature of the air increases. The activation energy was calculated by using the Arrhenius equation for all simulators. Why diffusion coefficients of carbon in bcc and […]
