Answer: Technical sales engineer

Explanation:

An analysis engineer makes use of data and other technical information in order for him or her to be able to analyze a project plan, and provide necessary solutions.

Technical sales engineers gives their clients the needed support and sales advice for their business to thrive. Technical sales engineers helps their clients in giving technical advices, answering queries, as well as introducing new products.

Design engineers are the engineers that study, and develop ideas that will be used for new products. Sometimes, they also modify systems used in production so that organizational performance can be improved.

Inspection engineers are the engineers that looks at infrastructures and identify the problems affecting them e.g oil pipelines, roads, bridges, etc so that accidents will be prevented.

Consulting engineer is an engineer that deals with the planning, and infrastructures. Their work benefits the society as a whole.

Based on the above explanation, the answer is technical sales engineer.

A dual voltage/dual resistance AC hair dryer can be used with a 120 V or 230 V power supply. A switch allows the user to set the
NISA [10]

Answer:

The power is  p= 5621 W

Explanation:

In order to obtain the power it consumes we need to first obtain the resistance of the hair dryer at 120 V

                  R = \frac{V^2}{P} = \frac{(120 V)^2}{1530W} = 9.411 \Omega

Now the power supplied in Europe at their voltage of 230V would be

                           P = \frac{V^2} {R} = \frac{(230V)^2}{9.411 \ \Omega} = 5621 W

Looking the power obtain we see that it is higher than 1530 W so this would cause the dryer to smoke.

A gas contained in a piston cylinder assembly undergoes a process from state 1 to state 2 defined by the following relationship
Minchanka [31]

Answer:

V2 = final volume = 8.3m^3

Explanation:

Given P1 = 445 kPa, V1 = 2.6 m^3, P2 = 140 kPa

From PV = constant; P1V1 =P2V2 , where V2 = final volume

V2 = P1V1/P2

Substituting in the equation ;

V2 = 445 x 2.6 / 140

V2 = final volume = 8.3m^3

What is the area enclosed by the cycle area of the Carnot cycle illustrating on a T-s diagram?
gayaneshka [121]

Answer:

Heat

Explanation:

Carnot cycle:

  Carnot cycle is the ideal cycle for all working engine .Carnot cycle all processes are reversible.It have fore process Out of two are constant temperature process and other two are isentropic process(reversible adiabatic).

We know that area under T-s diagram represents the heat.

So Q=\int Tds

From cycle we can say that

q_{in}=T_2\left ( s_2-s_1 \right )

q_{out}=T_1\left ( s_2-s_1 \right )
