2. The oil sands of Alberta, Canada contain commercially viable quantities of oil. The average properties of the oil sands are as follows: - Initial bulk density = 2.06 Mg/m3 - Initial porosity = 0.35 - Oil saturation = 70% of pore volume - Specific gravity of soil solids = 2.68 - Specific gravity of oil = 0.86 - Note: assume pore contain only oil and water (no air)
A truck is traveling down a road with a 3-percent grade at a speed of 55 mi/h when the brakes are applied. Knowing the coefficients of friction between the load and the flatbed trailer (us= 0.40) and (uk= 0.35)
This weir is to be replaced by an uncontracted horizontal weir that will maintain the same upstream depth. Determine the height of the weir if the discharge coefficient is based on the following equation: C = 1.78 * 0.22(H/p)
A nylon thread is to be subjected to a 10-N tension. Knowing that E=3.2 GPa, that the maximum allowable normal stress is 40 MPA, and that the length of the thread must not increase by more than 1%
A rectangular channel 2.0 m wide carrying a discharge of 2.5 m3/s is to be fitted with a weir at its downstream end to provide a means of flow measurement as well as to cause heading-up of the water surface.
The difference in water level is 60ft. Determine the size of pipe for a water temperature of 60 degrees Fahrenheit. Apply The Darcy-Weisbach equation.
An automobile has been designed to maintain a constant speed of 55 mph on a +5% grade. The weight of the vehicle when fully loaded is 6000 lbs. What is the total resistance in still air of this vehicle? What would be the resistance on a level road? W..
Locate the image using both the spherical mirror equation and a ray diagram and identify if it is real or virtual, upright or inverted, and smaller or larger.
The center post B of the assembly has an original length of 124.7mm, whereas posts A and C have a length of 125mm. If the caps on the top and bottom can be considered rigid
A rectangular steel plate with thickness t=0.625 inches is subjected to normal stresses sigma x and sigma y.The strain in the x direction is known to be 0.00065 and the strain in the y direction is known to be 0.0004
A triangular shaped swale is to retain the runoff from a catchment with a design runoff rate of 0.01 m3/sec. The longitudinal slope of the swale is to be 1.5% with side slopes of 5:1 (H:V).
A developer wants to provide access to a new building from a driveway placed 1000 ft upstream of a busy intersection. He is concerned that queues developing during the red phase of the signal at the intersection will block access.
The coordinates for Point A, Point B and Point C are 5859.28N, 9331.56E and 8501.95N, 7911.60E and 10,500.00N, 8000.00E respectively. An angle right of 220°31'00" is turned when the backsight is B
