Are you worried about the toughest competition in the job market? Are you panic of facing the interview among the competitors? Thermal engineering is all about the transfer of heat, thermodynamics, energy conversion and HAVE applications. Thermal engineering may be practised by mechanical engineers and chemical engineers. The role of mechanical engineer is to have good solid knowledge through academic coarse work, good knowledge of heat transfer, fluid flow, thermal management and excellent communication skills.

Mechanical Design Interview Questions and Answers

Following are frequently asked mechanical engineering interview questions for freshers as well as experienced engineering candidates. The second law of thermodynamic depicts that the total entropy of an isolated system can never reduce over time. The shear center is a center where the force can act with no twist, whereas elastic center is located at the center of gravity. It is one of the types of a joint that are used to connect two rods, which are under compressive or tensile stress. This joint is made of steel or iron. Cotter joint is used for connecting a piston rod to the crosshead of the reciprocating steam engine.

Define heat transfer? Heat transfer can be defined as the transmission of energy from one region to another due to temperature difference. What is conduction? Heat conduction is a mechanism of heat transfer from a region of high temperature to a region of low temperature within a medium [solid, liquid or gases] or different medium in direct physical contact. The rate of heat conduction is proportional to the area measured normal to the direction of heat flow and to the temperature gradient in that direction. Define Thermal conductivity. Thermal conductivity is defined as the ability of a substance to conduct heat.

Answer : Heat transfer can be defined as the transmission of energy from one region to another due to temperature difference. Answer : Heat conduction is a mechanism of heat transfer from a region of high temperature to a region of low temperature within a medium [solid, liquid or gases] or different medium in direct physical contact. Answer : The rate of heat conduction is proportional to the area measured normal to the direction of heat flow and to the temperature gradient in that direction. Answer : Thermal conductivity is defined as the ability of a substance to conduct heat. It is fluid motion is produced due to change in density resulting from temperature gradients, the mode of heat transfer is said to be free or natural convection. It is defined as the ratio of product of inertia force and buoyancy force to the square of viscous force. Laminar flow: Laminar flow is sometimes called stream line flow.

Thermodynamics Interview Questions

Engineering Tolerances are allowable variation from given dimensions. In other words, it is the total amount by which a given dimension may vary without affecting product function. The production of closely mating parts, without tolerances is economically unfeasible. This will increase the rejection rate and manufacturing cost. Therefore, tolerances are used with part dimensions to facilitate manufacturer and reduce cost.

Mechanical Engineering Practice Mcq Question and Answer

Thermal Engineering is a specialised sub-discipline of Mechanical Engineering that deals exclusively with heat energy and its transfer between not only different mediums, but also into other usable forms of energy. Bansal is very useful for Mechanical Engineering MECH students and also who are all having an interest to develop their knowledge in the field of Design, Automobile, Production, Thermal Engineering as well as all the works related to Mechanical field. This Book provides. In this article, we test your study on thermal engineering with thermal engineering questions and answers. As you know that thermal engineering is a branch of science which deals with the energies acquired by the gas and vapour, the conversion of these energies into heat and mechanical work and their relationship with properties of the system.

Thermodynamics is the branch of physics that studies the relationship between heat, work, energy and temperature. It provides information about the flow of energy and how thermal energy energy of a substance or system because of its temperature converts to and from other forms of energy. The laws of thermodynamics put a light on how the energy of the system is changing and whether the system is performing any work on its surroundings.

Solved examples with detailed answer description, explanation are given and it would be easy to understand. Here you can find objective type Mechanical Engineering Thermodynamics questions and answers for interview and entrance examination. Multiple choice and true or false type questions are also provided. You can easily solve all kind of Mechanical Engineering questions based on Thermodynamics by practicing the objective type exercises given below, also get shortcut methods to solve Mechanical Engineering Thermodynamics problems. A cycle consisting of one constant pressure, one constant volume and two isentropic processes is known as.
