APPENDIX B: ZVD Program Code 00-05 Examples
Example (1): User Defined Units in Pump RPM
Given: Code 01 – 00 = 60 Hz
Motor RPM @ 60 Hz = 1800 RPM
Reducer Ratio = 21.420 : 1
Then: Pump RPM @ 60 Hz = 1800 / 21.420 = 84.03 RPM
Code 00 – 05 = Pump RPM / Code 01 – 00
Code 00 – 05 = 84.03 / 60 = 1.40
Example (2): User Defined Units in Pump RPM
Given: Code 01 – 00 = 60 Hz
Motor RPM @ 60 Hz = 1800 RPM
Reducer Ratio = 5.091 : 1
Then: Pump RPM @ 60 Hz = 1800 / 5.091 = 353.565 RPM
Code 00 – 05 = Pump RPM / Code 01 – 00
Code 00 – 05 = 353.565 / 60 = 5.89
Example (3): User Defined Units in Flow Rate (cc /
minute)
Given: Code 01 – 00 = 60 Hz
Motor RPM @ 60 Hz = 1800 RPM
Reducer Ratio = 11.202 : 1
Pump Capacity = 2.4 cc / revolution
Then: Pump RPM @ 60 Hz = 1800 / 11.202 = 160.686 RPM
Pump Flow Rate @ 60 Hz = 160.686 RPM x 2.4 cc /
Rev = 385.646 cc / minute
Code 00 – 05 = Pump Flow Rate / Code 01 – 00
Code 00 – 05 = 385.646 / 60 = 6.43
Example (4): User Defined Units in Flow Rate (gal / hour)
Given: Code 01 – 00 = 60 Hz
Motor RPM @ 60 Hz = 1800 RPM
Reducer Ratio = 11.238 : 1
Pump Capacity = 15.0 cc / revolution
Then: Pump RPM @ 60 Hz = 1800 / 11.238 = 160.171 RPM
Pump Flow Rate @ 60 Hz = 160.171 RPM x 15.0 cc /
Rev = 2402.56 cc / minute
Pump Flow Rate in cc / hour @ 60 Hz = 2402.56 cc/m
x 60 m/hr = 144,154 cc/hr
Pump Flow Rate gal/hr @ 60 Hz = 144,154 cc/hr x
.0002642 gal/cc = 38.09 gal/hr
Code 00 – 05 = Pump Flow Rate / Code 01 – 00
Code 00 – 05 = 38.09 / 60 = 0.63
Example (5): User Defined Units in Flow Rate (gm /
minute)
Given: Code 01 – 00 = 60 Hz
Motor RPM @ 60 Hz = 1800 RPM
Reducer Ratio = 22.585 : 1
Pump Capacity = 1.2 cc / revolution
Fluid Specific Gravity = 1.1 gm / cc
Then: Pump RPM @ 60 Hz = 1800 / 22.585 = 79.699 RPM
Pump Flow Rate @ 60 Hz = 79.699 RPM x 1.2 cc/Rev
= 95.64 cc / minute
Pump Flow Rate in gm/min @ 60 Hz = 95.64 cc/m x
1.1 gm/cc = 105.2 gm/min
Code 00 – 05 = Pump Flow Rate in gm/min/Code 01 – 00
Code 00 – 05 = 105.2 / 60 = 1.75
Example (6): User Defined Units in Flow Rate (pounds /
hour)
Given: Code 01 – 00 = 60 Hz
Motor RPM @ 60 Hz = 1800 RPM
Reducer Ratio = 5.057 : 1
Pump Capacity = 4.5 cc / revolution
Fluid Specific Gravity = 1.25 gm / cc
Then: Pump RPM @ 60 Hz = 1800 / 5.057 = 355.94 RPM
Pump Flow Rate @ 60 Hz = 355.94 RPM x 4.5 cc / Rev
= 1601.7 cc / minute
Pump Flow Rate in gm/min @ 60 Hz = 1601.7 cc/m x
1.25 gm/cc = 2002 gm/min
Pump Flow Rate in lb/min @ 60 Hz = 2002 gm/m x
.0022 lb/gm = 4.417 lb/min
Pump Flow Rate in lb/hr @ 60 Hz = 4.417 lb/min x 60
min/hr = 265.0 lb/hr
Code 00 – 05 = Pump Flow Rate in lb/hr/Code 01 – 00
Code 00 – 05 = 265.0 / 60 = 4.42
