How do you calculate water cement ratio and cement content for a design concrete mix? The water to cement ratio is calculated by dividing the water in one cubic yard of the mix ( in pounds) by the cement in the mix (in pounds). So if one cubic yard of the mix has 235 pounds […]
What are the 3 extensive properties?
What are the 3 extensive properties? Extensive Properties Volume. Mass. Size. Weight. Length. Which of the following is an extensive property of matter? Some examples of intensive properties are color, taste, and melting point. Extensive properties vary according to the amount of matter present. Examples of extensive properties include mass, volume, and length. 1. Is […]
What are the advantages of closed loop system?
What are the advantages of closed loop system? Closed loop control systems are more accurate even in the presence of non-linearities. The sensitivity of the system may be made small to make the system more stable. The closed loop systems are less affected by noise. What is an example of a closed loop system? Two […]
What are 2 methods of searching an array?
What are 2 methods of searching an array? Searching Algorithms Sequential Search: In this, the list or array is traversed sequentially and every element is checked. For example: Linear Search. Interval Search: These algorithms are specifically designed for searching in sorted data-structures. What type of algorithm is performed in linear search? Linear search is a […]
How do you find the critical points of a function?
How do you find the critical points of a function? A critical point occurs when the derivative is 0 or undefined. If our equation is f(x)=mx+b, we get f'(x)=m. So if the function is constant (m=0) we get infinitely many critical points. How do you find the function of two variables? First, take the partial […]
Does a TV use chemical energy?
Does a TV use chemical energy? A television set is another device that operates by the transformation of energy. An electrical beam from the back of the television tube strikes a thin layer of chemicals on the television screen, causing them to glow. In this case, electrical energy is converted into light. How does a […]
Does the cutting force increase with the following why a increasing depth of cut B decreasing rake angle?
Does the cutting force increase with the following why a increasing depth of cut B decreasing rake angle? It is logical that the cutting force increases as the depth of cut increases and rake angle decreases. Deeper cuts remove more material, thus requiring a higher cutting force. What is rake angle in machining? Rake angle […]
What is simple Vapour compression cycle?
What is simple Vapour compression cycle? Simple vapour compression cycle is a system where the suitable working substance is used, called as a refrigerant. It evaporates and condenses at pressure and temperature closes to atmospheric conditions. The refrigerant used is carbon dioxide, ammonia etc. Why is multi stage compression with intercooling adopted? Advantages of multi-stage […]
