ASPE CPD Study Questions AH Latest
Version Graded A+

What is specific gravity in relation to water?


✔✔Specific gravity is a dimensionless number that compares the density of a substance to the

density of water, helping to determine how heavy a substance is relative to water.




How is specific gravity measured?


✔✔Specific gravity is measured using a hydrometer, which floats in a liquid, providing a reading

based on how deep it sinks.




Why is specific gravity important in water quality testing?


✔✔Specific gravity helps assess the concentration of dissolved substances in water, indicating

the water's quality and potential contaminants.




What is the formula for calculating velocity in fluid flow?


✔✔Velocity can be calculated using the formula: Velocity (v) = Flow Rate (Q) / Cross-Sectional

Area (A).




1

,How does temperature affect the specific gravity of water?


✔✔As temperature increases, the density of water decreases, leading to a lower specific gravity

value.




What factors influence the velocity of water in a pipe?


✔✔Factors influencing water velocity include pipe diameter, fluid viscosity, pressure difference,

and surface roughness of the pipe.




What is a pressure water test used for?


✔✔A pressure water test is used to determine the integrity of plumbing systems by checking for

leaks and ensuring the system can handle designated pressure levels.




What is the typical range for specific gravity of fresh water?


✔✔The specific gravity of fresh water is typically around 1.0 at 4°C (39°F), where it is densest.




How can you determine the pressure of water in a system?


✔✔Water pressure can be measured using a manometer or pressure gauge, which indicates the

force exerted by the water on a surface.




2

,What does it mean if water has a specific gravity greater than 1?


✔✔If water has a specific gravity greater than 1, it indicates that the substance is denser than

water and will sink when placed in it.




What is the relationship between pressure and flow velocity in fluid dynamics?


✔✔According to Bernoulli's principle, an increase in the speed of a fluid occurs simultaneously

with a decrease in pressure or potential energy in the fluid.




How is water flow velocity calculated in an open channel?


✔✔In an open channel, flow velocity can be calculated using the Manning equation, which

considers the channel's slope, roughness, and hydraulic radius.




What equipment is typically used to perform a pressure test on water lines?


✔✔A pressure test on water lines is typically performed using a pressure gauge and a pump to

apply pressure to the system.




Why is understanding specific gravity essential for environmental assessments?


✔✔Understanding specific gravity is essential for environmental assessments because it helps

evaluate pollutant concentrations and the potential impact on aquatic ecosystems.

3

, What happens to water pressure as depth increases in a fluid column?


✔✔As depth increases in a fluid column, water pressure increases due to the weight of the water

above, following the hydrostatic pressure principle.




How can specific gravity measurements be useful in industrial applications?


✔✔Specific gravity measurements are useful in industrial applications for quality control,

ensuring material consistency, and detecting product adulteration.




What role does water velocity play in erosion processes?


✔✔Water velocity affects erosion processes by determining the ability of water to transport

sediment; higher velocities can increase erosion rates along riverbanks and streambeds.




What is the significance of performing a water pressure test on newly installed piping?


✔✔Performing a water pressure test on newly installed piping ensures the integrity of the

system, identifies leaks, and verifies that the piping can withstand operational pressures.




How do changes in temperature affect water density and specific gravity?
