An electric motor produces 500w of electrical power. it is connected to a refrigerant compressor with 134a refrigerant. 1) what is the hp of the motor?

2) if the efficency from the motor to refrigerant compressor is 0.92, how much power is delivered to the compressor in w?

1) 0.67HP

2)

Explanation:

1)In order to solve the problem we use the conversion between HP and Watts:

1HP=746Watts

So:

500W*(1HP/746W)=0.67HP

2)The power delivered is equal to the ideal power multiplied the motor's efficiency:
