Answer:
It is a perpetual motion machine.
Explanation:
The claim of an inventor is not valid because a device can not deliver more energy than it input or there is no device that can produce more energy than it input. Therefore, the compressor cannot produce more energy as compared to another conventional heating system that runs by the e power input. However, the claim of inventor violates the rule or first law of thermodynamics and So, it is only a perpetual motion of first kind PMM1.
Answer:
L = spindle
M = lower ball joint
part without the letter showing = steering knuckle
Explanation:
Answer:
This Time is optimistic as calculated are based on ideal case. Considering the real case, refrigerated space will gain heat from surrounding and increase work load and hence requires more time to cool watermelons to required temperature.
Explanation:
Given:
Power input= =450 W
COP=1.55
N=5 watermelons
Mass of each watermelon=10 Kg
Initial Temperature=
Final Temperature=
Specific heat=
Required:
How long it will take for the refrigerator to cool watermelons?
Solution:
Heat Removed from watermelons is:
Rate of heat removed:
Time is Calculated as:
This Time is optimistic as calculated are based on ideal case. Considering the real case, refrigerated space will gain heat from surrounding and increase work load and hence requires more time to cool watermelons to required temperature.
