Mcqs Of First Law Of Thermodynamics Engineering Thermodynamics

A rigid tank of quantity of 8 m3 is being filled up with air from a pipeline connected via a valve. Initially the valve is closed and the tank is assumed to be completely evacuated. The air stress and temperature contained in the pipeline are maintained at 600 kPa and 306 K, respectively.

Competitive Mechanical’s imaginative and prescient is to supply complete Study Materials, Discussion of earlier year’s questions, and Strategy for upcoming exam for mainly Diploma in Mechanical Engineering Students. First legislation would not help to foretell whether or not the system will or not endure a change. The term which can differentiate thermodynamics from different sciences is ____.

Consider 1 kg of an ideal fuel at 1 bar and 300 K contained in a inflexible and perfectly insulated container. The particular heat of the fuel at fixed volume cv is equal to 750 J-kg-1K-1. Assume that the container does not take part in the thermodynamic interplay. The ultimate pressure of the fuel might be ______ bar . Thus, the First legislation of thermodynamics furnishes the relationship between heat, work and the internal power of the system i.e., the properties of the systrem. Specific warmth of air at constant strain is equal to 0.

First law of thermodynamics furnishes the relationship between___… At steady state, 500 kg/s of steam enters a turbine with particular enthalpy equal to 3500 kJ/kg and specific entropy equal to six.5 kJ-kg-1K-1. It expands reversibly within the turbine to the condenser stress. Heat loss occurs reversibly within the turbine at a temperature of 500 K. If the exit specific enthalpy and particular entropy are 2500 kJ/kg and 6.three kJ-kg-1K-1, respectively, the work output from the turbine is _________ MW .

The first law of thermodynamics tells us that the common temperature of the universe will change for reasons unknown. If you think that you understand what the primary regulation of thermodynamics means, suppose again. It isn’t a principle, it means something that cannot be scientifically proven, and it’s a legislation of nature. This is a regulation of physics that can be utilized to predict how the typical temperature of a solid physique will behave. Because every thing is going to be constant, it’s fully impossible to foretell what’s going to occur subsequent. I don’t believe that the primary law of thermodynamics furnishes the connection between our actions and our outcomes.

If we had been able to use a theoretical model to foretell what’s going to happen next, it will be extremely advanced, and we can’t do that. Please log in or register to reply this query. Examtown.com is a complicated query and answer service that will help how to tie up hair without ruining curls you to become sensible and also allow you to to score excessive. It is the notable preparation and follow middle for competitive, board, entrance exams, certifications and interviews. A fuel is compressed in a cylinder by a movable piston to a quantity one-half its unique volume.

For example, if you flip a coin, you realize the primary time you flip it a certain means, however the possibilities of that taking place again are very small. Similarly, you understand you’ll flip your coin in the same method the primary time, however it’s hard to foretell precisely what is going to happen subsequent. First regulation of thermodynamics furnishes the relationship between Heat, work and properties of the system.
