Question
Chapter 5, Problem 1RQ
To determine
Types of soils and how they are classified
Expert Solution & Answer
Answer to Problem 1RQ
Soils are classified based on particle size and physical properties. The types of soil include gravel, sand, silt, clay, and organic matter.
Explanation of Solution
The classification of soils is done based on the particle size and their physical properties. They are segregated with the help of sieve analysis. They are mostly classified in the following five types,
A. Gravel:
It is a hard rock material with particle size greater than 6.4mm but less than 76mm.
B. Sand
The particle size ranges from 0.050mm to 6.3mm which are too small to handle individually. Sand possesses high permeability and therefore has excellent drainage characteristics.
C. Silt
The particle size of silt ranges from 0.002mm to 0.05mm. It is also known as fine sand.
D. Clay
It is a cohesive soil and it expands when it absorbs water. The particle size of clay is less than 0.002 mm.
E. Organic matter
It refers to partly decomposed plants and animals.

A borrow-pit (i.e., a place where soils are excavated, to then be placed elsewhere for construction projects) has been identified with e = 0.74, emax = 0.9, emin = 0.5. To avoid excessive road deformations, the soil will be compacted to a relative density of DR = 90% when placed in the embankment. Your boss estimates that extracting 100,000 m^3 of material from the borrow-pit should be enough for this project. Is your boss correct, or is more material than that needed? To decide, answer these questions: a) What volume of soil, as placed, is required to build the embankment? [Tip: draw the embankment] b) What is the void ratio of the material when placed in the embankment? c) What is the relative density of the material in the borrow-pit? d) When soil is extracted from the borrow-pit and then compacted it the embankment, how do…arrow_forward
- There are 20 cars traveling at constant speeds on a 1 mile long ring track and the cars can pass each other freely.

The outlet of the drawn tubing at the drinking water trough discharges to the atmosphere as a water jet. The outlet of the pipe is approximately 12 ft higher than the water surface of reservoir. Expected water temperature is 70ᵒF. Your objective is to select a pump and check its performance for the specified system. Your tasks include: 1. Determine total dynamic head (TDH) operating against the pump for the design flow rate. Neglect minor losses. Note that H-W is not appropriate for this water temperature, and you need to use D-W. 2. Use the TDH and Qdesign to approach a pump vendor. She provides you the attached four pump performance curves for your consideration. 3. Select the appropriate pump based on the fit of the selection point on the pump performance curves. 4. Develop the system curve. 5. Determine the pump operating point and record the system operating conditions…arrow_forward
