From the distances and deflections computed in Problem 11.8, compute the chords (six) required for layout directly on offsets 50 ft right and 50 ft left of the c L.
Problem 11.8,
Given PI at 15 + 78.28, Δ = 36°1030 RT, and R = 1,150 ft, compute the deflections for even 100-ft stations.
An activated sludge system treats 1500 m3/day of raw wastewater with a BOD of 250 mg/L. The reactor volume is 375 m3. The kinetic parameters were determined to be: x = 3 day-1, Y = 0.55 kg SS/kg cells, and Ks = 150 mg/L.
Assume the capacity of a pile supporting a transmission tower is modeled with a log-normal random distribution with a mean of 250 tons and a c.o.v. of 20%.
One way to treat amd is to treat the metals in a holding pond. The first order rate constant is 10/day. The concentration in the water must be below 5 ppm. How long in hours will it take to reduce the concentration from 250 ppm to 5 ppm
The heat exchanger consists of 12 m of copper tubing that is 2 cm in diameter with 19 return bends. The flow rate is 3 x 10-4 m3/s. Water enters at 20 C and exits at 80 C. The elevation difference between the entrance and the exit is 0.8 m.
A closed system of 0.123kg undergoes a frictionless, quasi-static process along the path PV=C from 100kpa to a final state where the volume is twice the initial volume. During the process 8140 N-m of work is done by the system. What is the final spec..
If the amount of heat transfer in the HE unit is 2460 kJ per kg of steam, what is the magnitude of shaft work obtained from the turbine in kW?

The 1-hr UH in the table was recorded for a particular watershed. Determine the size of the watershed in acres and then convert the 1-hr UH into a 3-hr UH for the watershed.
What is the span length of a uniformly loaded simple beam with a wide-flange cross section if the maximum bending stress is 12,000 psi, the maximum deflection is 0.1 in, the height of the beam is 12 in
As shown, a load of mass 10 kg is situated on a piston of diameter D1 = 140 mm. The piston rides on a reservoir of oil of depth h1 = 42 mm and specific gravity S = 0.8.
A gate (shaped like .25 of a cylinder with radius R=3m) is used to control the flow of water through a canal.The height of the water in the tank is 30m. How much force must be applied to keep the gate from opening? The gate is 30m wide.
A certain stell tape, for wich the the coefficient of expansion is 0.00000645, is exactly 100 ft long68 farenheit. at 15 farenheiit the length of the tape is howmany feet?
