Question

efficiency of engine is 40% the temperature of source is 327C find the temperature of sink

Answer 1

Answer:

Given:

Efficiency of Engine = 40%

Source Temperature = 327°C

To find:

Temperature of Sink

Conversion:

327°C = 327 + 273 = 600K

Calculation:

$\eta = 1 - \dfrac{sink \: temp.}{source \: temp.}$

$= > 40\% = 1 - \dfrac{sink \: temp.}{600}$

$= > 0.4 = 1 - \dfrac{sink \: temp.}{600}$

$= > \dfrac{sink \: temp.}{600} = 0.6$

$= > sink \: temperature = 360 \: K$

So final answer is

$\boxed{sink \: temp. = 360 \: K}$

Answer 2

QUESTION:-

efficiency of engine is 40% the temperature of source is 327C find the temperature of sink.

GIVEN:-

•efficiency of engine is 40%

•the temperature of source is 327°C .

FIND:-

Temperature of Sink.

Conversion:-

°C $\implies$ K.

.°. 327°C = 327 + 273 = 600K

SOLUTION:-

$\implies$ $\eta$ =1 - sink temperature / source temperature.

$\implies$ 40%=1 - sink temperature / 600k

[NOTE:- 40% $\implies$ 0.4 ]

$\implies$ .°. 0.4-1=0.6

$\implies$ .°.0.6=sink temperature / 600k

$\implies$ .°.sink temperature =600×0.6

$\implies$ .°.sink temperature =360k.
