Three pipes in a parallelsystem run between points A & B on a water distribution network delivering 400L/s. Pipe 1 is a 350 mm PVC main 4000 m long, Pipe 2 is a concrete pipe 250 m long and 80 mm in diameter, and Pipe 3 is cast iron pipe of 100 mm diameter that is1000 m in length with an absolute roughness of5x10-4 m.
Minor loss coefficientsfor Pipes 1, 2 & 3 are 5, 15 and 18 respectively. Determine the head-loss between points A & B.
The height of the instrument during this measurement was 1.60m From the same setup from point A, the zenith angle and slope distance toward point B are measured as 83deg 32'30" and 186.23m respectively, while the elevation of point B is 315.34m AM..
A cohesionless soil sample was subjected to a triaxial test. The sample failed when the minor principal stress (confining pressure) was 1200 lb/ft^2 and the deviator stress was 3000 lb/ft^2.
Knowing that G = 11.2 x10^6 psi, determine the maximum shearing stress in each shaft when a torque of T of magnitude 420kip*ft is applied to the flange indicated. And the torque T is applied to flange B.
inability and green engineering can be integrated in the four components of materials science and engineering?
A worker slowly moves a 50-kg crate to the left along a loading dock by applying a force P at corner B as shown. Knowing that the crate starts to tip at about the edge E of the loading dock when a= 200mm
What is the alkali-aggregate reaction? List some of the rock types that are vulnerable to attack by alkaline solutions. Discuss the effect of aggregate size on the phenomenon.
Determine the lengths and bearings of the sides of a closed polygon traverse whose corners have the following x and y coordinates: A(5000.00, 5000.00) B(5289.67, 5436.12) C(4884.96, 5354.54) D(4756.66, 5068.37)
Four liters of water are equilibrated with a gas mixture containing carbon dioxide at a partial pressure of 0.3 atm. Henry's law constant for H2CO3* solubility is 2.0g/L-atm.
All four of B's wheels were locked and skid marks indicate that B slid 2 m after impact. If you estimate the coefficient of kinetic friction between B's tires and the road to be 0.4 and the coefficient of restitution to be 0.4
A composite price index for the cost of vegetarian foods called eggs, artichokes, and tofu (EAT) was 330 ten years ago and has averaged an annual increase of 12% since. Calculate the current value of the index.
Determine whether these conditions are true or false.
A biological reactor is used to treat wastewater from a small community (Q = 100,000 gpd). The influent BOD5 concentration to the reactor is 200 mg/L and the required effluent BOD5 concentration is 30 mg/L.
