Selecting orifices can be quickly implemented if the
pump stroke setting is correct but the pressure is too high. -
__Doubling the square inches__of the orifice open area__lowers the pressure 4____times.__ -
__Doubling the orifice diameter__increases the flow at the__same pressure by 4 times.__ -
__Doubling the pressure__increases the flow__by____1.41____times.__ -
__Tripling the pressure__increases the flow__by 1.73 times.__ -
__A pressure increase of 4 X’s using the same orifice results in a 2 X’s increase in flow__.
The E-6 injection pump delivers .1236 gallons of NH3
(.5241 lbs. N) per revolution at a 14 setting. This is full stroke. Each
setting under 14 reduces flow 7.14%. Maximum pump speed is 350 rpm or
43.3 gallons per minute at full stroke. The E-5 injection pump delivers
.0515 gallons of NH3 per revolution at the maximum setting. Determine acres per minute. Determine gallons per acre
of NH3 required to hit the per acre rate. NH3
weighs 5.14 lbs./G @ 60 |
