An aquifer is 2045 m wide and 28m tall. Its hydraulic gradient is 0.05 and hydraulic conductivity is 145 m/day.
a) Calculate Darcy's velocity of the groundowater as well as the amount of water that passes through the aquifer each day.
b) for the same aquifer, determine the seepage velocity of water through aquifer if the effective porosity is 32%.
what was involved in the first far-reaching, comprehensive study of Earth's oceans?
Determine the chemical oxygen demand (COD) of a mixture of 250 mg/l glutamic acid (C5H10N2O3) and 200 mg/l of glucose(C6H12O6).
We have a good sense of the fact the increased accuracy comes at a very increased price. Discuss 2 elements of an expensive GPS REC in relation to an inexpensive GPS REC.
A worker is to paint the walls of a square room 8ft high and 12 ft along each side. what surface area in square meters must she cover?
If the load effect has a mean value of 88 kips and a standard deviation of 1.8 kips. If the nominal material strength is 160 kips Determine the followings 1- The probability of failure of the structure under the nominal resistance and service load..
A 3400-lb car is traveling in third gear (ratio 2.5 to 1) on a level road at its top speed of 130 mi/h. The air density is 0.00206 slugs/cuft. The car has frontal area of 19.8 sqft, a drag coefficient of 0.28, a wheel radius of 12.6 inches, a driv..
The cart takes 5.00s to go from point A to point C, and the cart takes 1.90s to go from point B to point C. What is the cart's speed at point B. Express answer numerically to three significant figures in feet per second.
Calculate the force (in Kn) a punch press must exert if it is to punch out a large washer from a strip of 5-mm thick sheet steel with an ultimate shear strength of 400 MPa.
A structural component in the form of a very wide plate is to be fabricated from 4340 steel that was cooled using a fast cooling rate and has a yield strength of 1515 MPa and a fracture toughness (KIC) of 60.4MPam.
Two particles start from the same point along the same straight line and at the same instant. The first particle travels with a constant velocity v and the second with a constant acceleration.
A 1 cm diameter, 0.4 m long steel rod is to be used in an application where it will be subjected to an axial tensile force of 15kN. The factor of safety based on yield stress must be at least 1.5, and the axial deformation must not exceed 2 cm.
