-
Actual electrical power usage may differ due to varying power factor in AC systems.
-
Hydraulic calculations depend on precise fluid and system data; electrical sizing requires voltage, current, and load information.
Frequently Asked Questions
-
What does horsepower (water) measure?
-
Horsepower (water) indicates the theoretical mechanical power needed to move a volume of water against a certain head.
-
Why convert horsepower (water) to volt ampere?
-
This conversion helps correlate the mechanical hydraulic power to the equivalent electrical apparent power for integrated system design.
-
Does 1 horsepower (water) equal 1 watt?
-
No, 1 horsepower (water) equals approximately 746.043 volt ampere, which relates to apparent power, not just watts.
-
Can this converter be used for motor sizing?
-
Yes, it helps estimate motor power required based on hydraulic power needs.
Key Terminology
-
Horsepower (water)
-
Mechanical power required to move water against a specified head, calculated from flow rate, head height, and fluid properties.
-
Volt ampere [V*A]
-
Unit of apparent power in AC circuits, calculated as the product of RMS voltage and current, reflecting total power regardless of phase angle.
-
Apparent Power
-
Total power in an AC circuit, combining real power and reactive power, measured in volt amperes.
