A pipeline 900 ft long discharges freely at a point 200 ft lower than the water surface at intake. The pipe intake projects into the reservoir. The first 600 ft is of 10-in diameter, and the remaining 300 ft is of 6-in diameter. Find the rate of discharge, assuming f = 0.06. If the junction point C of the two sizes of pipe is 150 ft below the intake water surface level, find the pressure head just upstream of C and just downstream of C. Assume a sudden contraction at C.
The dye appears 14 days later in an observation well 75 ft away from the injection point. Compute the seepage velocity and estimate the hydraulic gradient in the aquifer if the porosity of the soil is 42%.
Knowing that these forces are equivalent to a force-couple system at C consisting of the force C= (- 8 N)i+ (4 N)k and the couple Mc =(360 N ⋅ m)i, determine the forces applied at A and B when Az = 2 N.
Trips can be classified by productions/attractions or origins/destinations. Which classification provides the direction of travel. Describe the product/outcome (e.g., production-attraction matrix) after each of the 4-step transportation planning pr..
The minimum clearance between the roadway and the waterline must be 6 feet. The PVI is located at station 19+00.00 with elevation 420.50 feet. The design speed of the curve is 55 mph, g1 is +3%, and g2 is -3.0%. PRT= 2.5 sec, 0.35 = friction facto..
Find the velocity of the air downstream of the restriction, and show that the enthalpy is essentially the same before and after the throttling process. Also find the change of entropy.
The discharge is 15 cubic meters per second with a bottom width=10m and side slopes of 1V:2H. If the discharge is increased to 20 cubic meters per second determine the new depth of flow

The difference between the total and static pressure before a shock is 75 psi. What is the maximum static pressure that can exist at this point ahead of the shock? The gas is oxygen.
At the bottom, an opening allows water to drain out at a rate, in lbm/s, that is proportional to H(t), the instantaneous height of water in the barrel, in ft: rate of water leaving from bottom = 9*H(t) .
The base line vector between the base and roving reciever is 8340m and has an accuracy of +/-(1to 2 cm +/-2ppm). What is the estimated uncertainty in the length of this vector
suppose a family of four, living in a home with an area of 100x5oft connects its stormwater drain to the sewer. Assume that 1in of rain falls over 1 day. what percentage increase will there be in the flow from their house over the dry weather flo..
Axis Chemical Company needs you to design a gravity sewer to convey 1,750 GPM of toxic waste. The pipe is to be glass-lined reinforced concrete (n = 0.009). Which pipe would you suggest the Joker use
