A permeameter with a cross-sectional area of 400 cm2 contains 3 soils in 50 cm thick layers. A total head difference of 2.0 metres results in a flow rate of 100 cm3/s. The head loss through the top layer of soil is 50 cm. The hydraulic conductivity of the bottom soil layer is 0.10 cm/s.a) What is the hydraulic conductivity of the other two soils?
b) If the total head, elevation head, and pressure head all equal zero at the bottom of the bottom soil layer, draw a graph of pressure head versus depth for the soil column.
If there are 50 vehicles on a 4000-ft highway lane and the average time headway between two adjacent vehicles is 2.2 seconds. A) Calculate traffic density in vehicle/mile (vpm) and average space headway in feet/vehicle (fpv).
Light-Voice Controlling System. We are planning to design a new light-voice controlling system. The voices will basically coordinate the crossing of a road by blind people. Suppose the crossing will be operated by two coordinated systems
A 4 X 8-ft solar collector has water circulating through it at the rate of 1.0 gallon per minute while exposed to sunlight with intensity 300 Btu/ft^2-hr.
A concentrated downward force of 2000 lb. is located 6' from the left support, and a uniformly distributed load of 200 lbs./lin. ft. begins 6' to the right end of the member. What force must be applied at each connection to maintain equilibrium?
The perpendicular distance between two parallel tangents of a reversed curve is 20m. The azimuth of the back tangents of the curve is 270 00 and the azimuth of the common tangent is 310.
The hull of a boat has a volme of 150m and the total mass of the boat when empty is 8560kg. determine how much load this boat can carry without sinking in a lake.
The condenser in a refrigerator receives R-134a at 700 kPa and 50C, and it exits as saturated liquid at 25 C, The flow rate is 0.1 kg/s,and the condenser has air in at an ambient temperature of 15 C and leaving at 35 C. Find the minimum flow rate ..
Ethyl acetate is made from acetic acid and ethyl alcohol. Let x = pounds of acetic acid input, y=pounds of ethyl acohol input, and z = pounds of ethyl acetate output. The relationship of output to input is: z^2/(1.47x - z)(1.91y - z) = 3.9.
Describe the use of productivity models for estimating land productivity. Provide details about various attributes that can be used and how the model is developed . Examples can be used to demonstrate model workability.
