Compilation of exam questions we got on mining technology for civil engineering students. Exam Question # 1. What are the types of detonators used in mining? Ans. High explosives are initiated by detonators or detonating fuses. A detonator is a small copper or aluminium tube containing essentially a small auxiliary charge of special explosive. A chemical reaction initiated by a [...]
Compilation of exam questions on IC engine for thermal engineering students. Exam Question # 1. Differentiate between two stroke cycle and four stroke cycle engines. Ans. Certain engines work on four stroke cycle principles while others work on two stroke cycle principle. Each cycle has its own advantages. (1) In two stroke cycle engine, every revolution has an active stroke; [...]
Compilation of interview questions on thermal engineering for students. Interview Question # 1. Define engineering thermodynamics. Ans. It is the science which analyses the problems related to the conversion of heat to work and vice-versa and changes in properties of the working fluids involved in such a conversion. The thermodynamic study deals with a concept of ideal processes and most [...]
Compilation of questions on thermal engineering for college students. Q. 1. State the first and second law of thermodynamics. Ans. First Law of Thermodynamics: (a) For a closed system which has passed through a cycle, the first law of thermodynamics states: When a closed system has passed through a cycle, the sum of the heat energy taken in across the [...]
Compilation of exam questions on thermal engineering for engineering students. Exam Question # 1. What is the difference between enthalpy and entropy? Ans. Enthalpy: A working substance in any state has a certain amount of internal energy. Besides, it also has some potential energy which is proportional to the absolute pressure and the specific volume i.e., to the product PV. [...]
Compilation of basic interview questions on thermodynamics for engineering students. 1. State Zeroth Law of Thermodynamics. When the two bodies one hot and the other cold, are placed in contact with each other, then the hot body loses heat and becomes colder and the cold body gains heat and becomes hotter, and this process continues till the thermal equilibrium is [...]
Compilation of interview questions and answers on thermal engineering for engineering students. 1. What is meant by Quasi-Static Process in Thermodynamics? Quasi means nearly or almost. So quasi-static process means nearly static process or nearly stationary process, or a process which proceeds with extreme slowness. Quasi-static process proceeds from one equilibrium state to another equilibrium state till the end of [...]
Compilation of lab viva questions and answers on thermal engineering for engineering students. 1. What are the Units of Measurement Used in Thermodynamics? Nowadays generally SI (System International) system of units is used. The basic units in this system are: Basic Units: The dimensions of all other quantities are derived from these basic units which are: A proper understanding of [...]
Thermal engineering question bank with answers! This will help you to learn about the frequently asked questions on thermal engineering. 1. What is Microscopic and Macroscopic Approach of Thermodynamic Study? There are two points of views: 1. Microscopic or Statistical Thermodynamics. 2. Macroscopic or Classical Thermodynamics, from which the behaviour of matter or working of a system can be studied. [...]
Here is a compilation of water engineering questions and answers for engineering school. 1. Define Storativity, Hydraulic Conductivity and Transmissivity of Aquifer. Explain with Diagram. Storage Coefficient or Storativity: Storage coefficient or Storativity is defined as the volume of water that an aquifer releases from or takes into storage per unit surface area of aquifer per unit change in the [...]
