Study Notes
Weather Mapping and Atmospheric Concepts
- A line on a weather map connecting points of equal atmospheric pressure is called an isobar.
- The component with the greatest quantity in dry air is nitrogen, making up about 78% of the atmosphere.
Soil Tests and Properties
- A soil test involving pouring fully saturated soil into a mold, aligned with Vaseline, is known as a laboratory shear test, used to assess soil strength.
- The term for the ratio of the mass of solid to the total volume of soil is bulk density.
- The ratio of the volume of voids to the total volume of the soil is referred to as void ratio.
Water Flow and Treatment
- Devices that regulate the distribution of water flow include valves and flow meters.
- A water treatment process that reduces dental caries in children is the addition of fluoride to drinking water.
- The process of removing fine residual suspended solids in wastewater treatment is called flocculation.
Fluid Mechanics Principles
- In flow net construction, the paths of equal energy are known as equipotential lines.
- If the average velocity at every cross-section of a stream is the same, the flow is characterized as uniform flow.
- The pressure head at the summit of a siphon, considering the datum line at the discharge end, is typically assumed to be zero if there is no head loss.
Specific Physical Concepts
- The average of the monthly means for the year is defined as the mean annual temperature.
- A fluid flowing through a pipe with a kinematic viscosity of 15x10^(-7) sq.m/s and a velocity of 0.8 m/s indicates laminar flow.
- The state where the metacenter (M) is below the center of gravity (CG) of a floating body results in unstable equilibrium.
- The dimensionless number representing the ratio of inertia forces to pressure forces is known as the Reynolds number.
- Devices installed in a pipe that extract energy from the system are called turbines or water wheels.
Miscellaneous Concepts
- The temperature range between the highest and lowest temperatures recorded for a particular day is referred to as the temperature span or temperature range.
- Water that flows from the atmosphere to the earth's surface in any form is known as precipitation.
- A system of streamline and orthogonal lines that shows the idealized flow pattern for a given system is termed a flow net.
Construction and Soil Classification
- In the Unified Soils Classification, soils are considered coarse-grained if less than 50% passes the No. 200 sieve.
- According to the National Structural Code of the Philippines, the maximum allowable slope for cut surfaces is typically detailed in site-specific guidelines.
- The process where water-saturated soil temporarily loses strength, behaving like a fluid, is known as liquefaction.
- A parameter that is NOT dimensionless in fluid mechanics includes quantities like velocity or pressure, as they depend on specific units.
