Calculating Accelerating Force for Linear Motion:
Where:
F = Force (lbs.)
W = Weight (lb.)
D
V = Change in Velocity (FPM)
t = Time to accelerate weight (seconds)
Where:
LRA = Locked Rotor Amperes
HP = Horsepower
kVA = Kilovolt-Amperes
E = EMF or Voltage (Volts)
Where:
60 Hz LRA = Locked Rotor Amperes
Freq. X = Desired frequency (Hz)
Engineering Constants
Temperature
0° C = Freezing point of wate
32° F = Freezing point of water = ° C
10 ° C = Boiling point of water at atmospheric pressure
21 ° F = Boiling point of water at atmospheric pressure
1.8° WF = 1° WC
0.252 Calories = 1 BTU
–270° C = Absolute zero
–459.6° F = Absolute zero
Length
1,760 Yards = 1 Mile
25.4 mm = 2.54 cm = 1 in.
3 ft. = 1 Yard
3.2808 ft. = 1 m
39.37 in. = 1 m = 100 cm = 1000 mm
5,280 ft. = 1 Mile
0.62137 Miles = 1 km
