An underground storage vault is to be constructed to serve as a detention pond for a heavily urbanized area. The walls of the vault will be vertical, but the flow will be sloped along its length to promote drainage. In plan view, the vault is rectangular with a length of 75 feet and a width of 40 feet. The slope of the floor, along the 75ft dimension, is 2%. The invert of the lower end of the vault is at an elevation of 123ft.
Determine the elevation vs. surface area relationship for the vault and use this information to calculate and graph the elevation-storage relationship. Use the average end area method.
Bars AB and CD are made of A-36 steel and 2014-T6 aluminum alloy,respectively. When the temperature is at 75degreeF, ACE is in the horizontal position.
A 3-mi section of a two-lane, two-way highway located in a mountainous terrain is to be designed to carry a peak hour volume of 750 vehicles. Using the operational level of analysis
The temperature was 200C, and the void ratio (e) of the soil was 0.43. Calculate the "Coefficient of Permeability" in "centimeters per second" (Given, k = (QL)÷(A Δh t)).
Helium enters an adiabatic steady-state nozzle at 200kPa and 124 degrees Celsius and 10m/s. At the nozzle exit the temperature of the helium is 100 degrees Celsius and the pressure = 150 kPa.
A 50 cm by 20 cm block weighing 150 N is to be moved at aconstant velocity of .8m/s on an inclined surface of 20 degreesfrom horizontal with a friction coefficient of .25.
