In order to keep an automobile operating, it is necessary to keep adding fuel as it is used up. Explain why this doesn't contrad

Semmy [17]

Answer:

There is conversion of energy from one form to another and this justifies the law of conservation of energy, which states that energy can neither be created nor destroyed but can be converted from one form to another.

Explanation:

The fuel added to automobile is a chemical energy, which provides thermal energy of the combustion engine of the automobile, which is then converted to mechanical energy of the moving parts of the automobile. Thus, there is conversion of energy from one form to another. This justifies the law of conservation of energy, which states that energy can neither be created nor destroyed but can be converted from one form to another.

Problem 10.012 SI A vapor-compression refrigeration cycle operates at steady state with Refrigerant 134a as the working fluid. S

pychu [463]

Answer:

a) 4.1 kw

b) 4.68 tons

c) 4.02

Explanation:

Saturated vapor enters compressor at ( p1 ) = 2.6 bar

Saturated liquid exits the condenser at ( p2 ) = 12 bar

Isentropic compressor efficiency = 80%

Mass flow rate = 7 kg/min

A) Determine compressor power in KW

compressor power = m ( h2 - h1 )

= 7 / 60 ( 283.71 - 248.545 )

= 4.1 kw

B) Determine refrigeration capacity in tons = m ( h1 - h4 )

= 7/60 ( 248.545 - 107.34 )

= 16.47 kw = 4.68 tons

C) coefficient of performance ( COP )

= Refrigeration capacity / compressor power

= 16.47 / 4.1 = 4.02

Attached below is the beginning part of the solution

when electric power is transmitted over long distance, line losses can be reduced by generating AC rather than DC voltage and by

Tanya [424]

When electric power is transferred over a long distance then, line loss can be reduced by high voltage and low current. Thus, option A is correct.

<h3>What is electric power?</h3>

The complete question is attached to the image below.

The electric circuit transfers the electric current then it is called electric power. The loss in the line over a larger distance is reduced by transferring AC instead of DC voltage.

The AC transmitted is of high voltage, and the power is low. The equation for current is given,

P = VI

The increase in the voltage causes the decrease in the current and in turn the resistance also reduces resulting in the loss of the power of the circuit to decrease.

Therefore, the loss is reduced by transferring high voltage and, low current AC.

In your own words, describe which engineering discipline (civil, mechanical, computer, or electrical) would be used to design a

Rudiy27

Answer:

Civil engineering.

Explanation:

Civil engineering is a branch of engineering whose mission is the design and construction of structures and buildings for civil use, understood as the use of these structures by society in the context of their daily life. Thus, for example, this branch of engineering is responsible for the construction of bridges, dams, tunnels, etc., being in all cases structures that facilitate the normal development of life in society.

In this context, the design and construction of a new sports arena, as long as it meets these parameters, would be carried out by a civil engineer.
