What color is a board sternlight
alukav5142 [94]

We can infer and logically deduce that the color of a boat's sternlight is white.

<h3>What is a sternlight?</h3>

A sternlight can be defined as a white light that is designed and developed to be placed as closely as possible and practical with the stern shining continuously (constantly).

By default, a sternlight is typically affixed to the boat in such a way that the light will shine out at an angle of 135 degrees (135°) from the back of the boat.

In this context, we can infer and logically deduce that the color of a boat's sternlight is white and it avails sailors and other persons the opportunity of determining and knowing the direction that a boat (vessel) is moving.

A heat engine uses fuel of energy content 43.1 MJ/kg and produces 17.4 kW of useful power. The heat rejection rate (through the
solmaris [256]

Answer:

a)27.9%

b)\dot{m}=3.06 \frac{Kg}{h}

Explanation:

Given that

Fuel energy content = 73.1 MJ/kg

Useful power = 17.4 KW

Heat rejection rate = 44.8 KW

From first law of thermodynamics

Heat addition rate =Heat rejection rate + Power out put

Now by putting the values in the above formula

Heat addition rate = 44.8 + 17.4

Heat addition rate =62.2 KW

We know that efficiency is given as follows

\eta =\dfrac{power\ out\ put}{Heat\ addition\ rate}

So

\eta =\dfrac{17.4}{62.2}

\eta =0.279

So the efficiency is 27.9%.

Now to find usage rate of fuel

Lets take usage rate is \dot{m}

Fuel energy content  x  usage rate of fuel = Heat addition rate

Now by putting the values

73100\times \dfrac{\dot{m}}{3600}=62.2

\dot{m}=3.06 \frac{Kg}{h}
