A 600’ long sewer pipe is being placed into a trench. Place the pipe at a gravity drainage slope of 2% towards station 6+00. The invert elevation at its beginning station (0+00) is 5395.00’. The pipe has an outside diameter of 1’ and a wall thickness of 1”.

a) Prepare an Excel table that lists the elevations for the top of the pipe for the stations 0+00, 1+00, 2+00, 3+00, 4+00, 5+00 and 6+00 *.

b) Calculate the invert elevation for the pipe at station 6+00. *

Note: Elevations for the top of the pipe are used to place leveling rods at those stations and control the depth of the pipe during construction (since the bottom of the pipe is then inaccessible).

Expert Solution

Station	Invert Elevation (ft)	Inner Diameter (ft)	Thickness of pipe wall (ft)	Longitudinal slope (%)	Top Elevation (ft)
0+00	5395	0.833	0.0833	2	5395.917
1+00				2	5393.917
2+00				2	5391.917
3+00				2	5389.917
4+00				2	5387.917
5+00				2	5385.917
6+00				2	5383.917

Building specifications in a city require that they mean breaking strength of a sewer pipe be greater than 2,500 pounds per foot of length. A manufacturer wants to sell pipes to the city and needs to show that their pipes exceed the specification. If a sample of 25 pipes is chosen and it is found that the sample has a mean breaking strength of 2,565 pounds with a standard deviation of 225 pounds, is there enough evidence at a 0.05...

The building specifications in a certain city require that the sewer pipe used in residential areas have a mean breaking strength of more than 2500 pounds per lineal foot. A manufacturer who would like to supply the city with sewer pipe has submitted a bid and provided the following information: An independent contractor randomly selected seven sections of the manufacturer’s pipe and tested each for breaking strength. The results (pounds per lineal foot) are as follows: 2610, 2750, 2420, 2510,...

Water is being pumped through a horizontal pipe that is 36.0 m long and 13.5 cm in diameter. A pump maintains a gauge pressure of 742 Pa at a large open tank at one end of the pipe. The other end of the pipe is open to the air. If this pipe is replaced by a second one of length 9 m and diameter 5.0 cm, what gauge pressure must the pump provide to give the same volume flow rate...

Two sewage pipes are mixed in a common sewer. The first pipe contains a strong acid, its pH is 3.00 and the flow rate is 50.0 L / s. The second conduct contains calcium hydroxide (a strong base) and its flow rate is 30.0 L / s. We want the common sewer to have a pH of 10.00. What is the molar concentration (in mol / L) of calcium hydroxide in the second pipe?

Four different coatings are being considered for corrosion protection of metal pipe. The pipe will be buried in three different types of soil. To investigate whether the amount of corrosion depends either on the coating or on the type of soil, 12 pieces of pipe are selected. Each piece is coated with one of the four coatings and buried in one of the three types of soil for a fixed time, after which the amount of corrosion (depth of maximum...

A new development is being planned, which will connect to the city ’s sanitary sewer system. This development will have 80 acres of medium-density residential assume 10 DU / acre and 2.8 persons per DU). Assume a per capita sewage rate of 90 gal/d/person. Additionally, a new community hospital will be constructed with 300 beds (assume 300 gal/d/bed). Assume I/I contribution of 10%. a. Calculate the mean sewer discharge (accounting for residential, commercial, and I/I flows). b. Calculate the maximum...

Two identical double-pipe heat exchangers are constructed of a 2-in standard schedule 40 pipe placed inside a 3-in standard pipe. The length of the exchangers is 10 ft; 40 gal/min of water initially at 80◦F is to be heated by passing through the inner pipes of the exchangers in a series arrangement, and 30 gal/min of water at 120◦F and 30 gal/min of water at 200◦F are available to accomplish the heating. The two heating streams may be mixed in...

A drainage pipe running under a highway is 20 meters long. One end of the pipe is open and the other is clogged by debris. The wind blowing across the open end causes oscillations in the pipe. a) If the speed of sound on that particular day is 340 meters per second, what will be the fundamental frequency of oscillation in the pipe? b) What will be the frequency of the highest harmonic audible to the human ear. (Assume that...
