On a pump station's electric motor a routine test should include a "Meger Test". The Meger Test evaluates

The motors RPMs
The motors work capacity in AMPS
The motors insulation integrity
The motors bearings and lubrication quaility
The motors true Horse Power

Correct Answer

A. The motors insulation integrity

Explanation

The "Meger Test" is a routine test that should be included in the evaluation of a pump station's electric motor. This test is specifically used to evaluate the motor's insulation integrity. It is important to assess the insulation integrity of the motor to ensure that there are no faults or breakdowns in the insulation system, which could lead to electrical failures or hazards. By conducting the Meger Test, any potential issues with the motor's insulation can be identified and addressed promptly, ensuring the motor's safe and efficient operation.

A misaligned irrigation head and / or a not-to-grade head can cause up to a

10% irrigation efficiency reduction
15% irrigation efficiency reduction
20% irrigation efficiency reduction
25% irrigation efficiency reduction
30% irrigation efficiency reduction

Correct Answer

A. 20% irrigation efficiency reduction

Explanation

A misaligned irrigation head and/or a not-to-grade head can cause a 20% irrigation efficiency reduction. This means that if the irrigation head is not properly aligned or if it is not at the correct grade, there will be a significant decrease in the efficiency of the irrigation system. This could result in water being wasted or not reaching the intended areas, leading to inefficient water usage and potential damage to plants or crops.

Total Dynamic Head (TDH) is important to irrigation pump stations, why

TDH is a term to discribe pressure
TDH is a term to reflect resistance in the pump
TDH is the resistance in the pump intake
TDH is the measurement of pump length
TDH is the term the discribes the relationship of water to gravity

Correct Answer(s)

A. TDH is a term to discribe pressure
A. TDH is a term to reflect resistance in the pump
A. TDH is the resistance in the pump intake

Explanation

Pumps aren't rated in PSI (pounds per square inch) as the PSI reading is dependant on the fluid's density

Evapotranspiration Rate (ET) is based on what climatic factors

Wind speed
Temperature
Humidity
Soil type
Sun exposure

Correct Answer(s)

A. Wind speed
A. Temperature
A. Humidity
A. Sun exposure

Explanation

Evapotranspiration Rate (ET) is determined by several climatic factors, including wind speed, temperature, humidity, and sun exposure. Wind speed affects the rate at which water evaporates from surfaces, as it helps in removing the water vapor. Temperature plays a crucial role in evaporation, as higher temperatures increase the kinetic energy of water molecules, leading to faster evaporation. Humidity affects evapotranspiration by determining the concentration gradient of water vapor between the surface and the atmosphere. Sun exposure provides the energy required for evaporation. Soil type, although not mentioned in the question, can also influence evapotranspiration by affecting water retention and availability.
