1.A Parshall flume with a throat width of 2.50 feet is used to measure discharge. If the measured depth, H, is 1.8 feet, what is the discharge? Need to know how to solve for the discharge.
2.A rear wheel drive 3000 lb drag race car has a 200 inch wheelbaseand a center of gravity 20 inches above the pavement and 140 inchesbehind the front axle. The owners wish to achieve an initialacceleration from rest of 15 ft/s2 on a level paved surface. What is the minimum coefficient of road adhesion needed to achieve thisacceleration? (assume γm=1.00)
From this I know that W=3000
L=200
h=20
lf=140
a=15
How to find μ, given acceleration?
After compaction the void ratio is reduced to 0.60. Determine: (a) Dry and moist unit weights before and after compaction (b) Degree of saturation after compaction.
Thomas Friedman's bestseller, The World is Flat, says that the world has been, in his words, "flattened" or leveled which increases accessibility and competition worldwide. What does this mean for engineering and for managers who deal with enginee..
A 25 mm diameter steel cylinder falls under its own weight at a uniform rate of 0.1 m/s inside a tube of slightly larger diameter. Castor oil of viscosity 0.25 N.s/m2 fills the spacing between the tube and the cylinder.
one gallon of paint(volume=3.78 x 10^ -3) covers an area of 25 m^2. what is the thickness in mm. of the paint on the wall
Axis of the hole is perpendicular to VP. Draw elevation, plan and development of the lateral surfaces of the pyramid.
Given: Q = 1000gpm, total head = 140 feet, pump efficiency = 70 percent, motor efficiency 65 percent, cost of electricity = 5 cent per kilowatt hour. What would be the daily cost of electricity to operate a pump 24 hours per day
What is the diameter of a circular concrete column needed to support a load of 300,000 pounds with a factor of safety of 2. Round the diameter up to the whole inch. The concrete ultimate strength is 3000 lb/in^2.
An empty air tank has a volume of 0.024 m3. The compressor on the tank is run until the pressure gauge reads about 65 psi (or 22,500 Pa). Assuming the temperature of the tank is 25 C, find the density of the air and the weight of the air in the ta..
