An air conditioner operating between 93°F and 70°F is rated at 4000 Btu/h cooling capacity. Its coefficient of performance is 27

lana [24]

Answer: $P_{in}=0.25\ Hp$

Explanation:

Given

Operating temperatures are

$T_L=70^{\circ}F\approx 294.261\ K$

$T_H=93^{\circ}F\approx 307\ K$

$COP$ is $27\%$ of Carnot refrigerator

$COP_{carnot}=\dfrac{T_L}{T_H-T_L}$

$COP_{carnot}=\dfrac{294.261}{307-294.261}$

$COP_{carnot}=\dfrac{294.261}{12.74}$

$COP_{carnot}=23.09\approx 23.1$

actual $COP=0.27 \times COP_{carnot}$

$COP_{actual}=6.237$

Also, $COP=\dfrac{\text{Desired effect}}{\text{Power in}}$

$6.237=\frac{4000}{P_{in}}$

$P_{in}=\frac{4000}{6.237}=641.33\ Btu/h$

$P_{in}=0.25\ Hp$

You ride your bike north for 100 m at a constant speed of 5 m/Your acceleration is…

inessss [21]

Answer:

our acceleration is 0 because there is a constant speed..

a = final speed - initial speed / time

final speed = initial speed ( since speed is constant)

therefore acceleration is 0
