160 psi x .62 = 99.2 psi
Assume only 5-foot lengths of cast iron pipe are used. Estimate the number of full lengths used in the construction of a pipeline, which measures 162’- 3”.
32
162.25’ ÷ 5’ = 32.45 = 32 full lengths
Refer to the previous question. Estimate the length of the additional piece required.
2’- 3”
.45 x 5’ = 2.25’ = 2’- 3” additional
Fill in the blank:
Refer to the previous question. The length of the scrap remaining after cutting is ______.
2’- 9”
6.55 x 5’ = 2.75’ = 2’- 9” scrap
Fill in the blank:
An assistant holds a rod on a benchmark of 7.50’ and the contractor takes a backsight rod reading of 4.50’. The contractor turns the level and reads the rod, placed on the septic tank inlet, giving a foresight rod reading of 7.25’. The inlet elevation of the septic tank is ______ feet.
Elevation 4.75
BM + BS = HI - FS = SE 7.50’ + 4.50’ = 12.00’ - 7.25’ = 4.75’
Which of the septic tank sizes listed below could hold 1,250 gallons in capacity?
5’- 0” x 5’- 6” x 6’- 2” inside dimension
Convert to cubic feet, 1,250 ÷ 7.5 = 166.66 cubic feet
Fill in the blank:
The inside of a single compartment septic tank measures 5’- 4” in width, 5’- 8” in depth, and has a capacity to hold 1,500 gallons. The inside length of the tank would be ______.
6’- 8”
33 (#7) Convert to cubic feet,
1,500 ÷ 7.5 = 200 cubic feet
L’ x W’ 200 cubic feet ÷ (5.33’ x 5.67’) = 6.61’ length
30.22 sq. ft. 6.61’ is 6 feet .61’ x 12 = 7.32” = 7 inches .32” x 16 = 5.12 = 5/16th
A water tank has a capacity to hold 1,000 gallons. Which of the following is true?
a. The water in the tank, when full, will weigh approximately 8,330 pounds
b. The volumetric capacity of the water tank is approximately 133 cubic feet
c. The volumetric capacity of the water tank is approximately 3,785 liters
d. All of the above are true
d. All of the above are true
1,000 gallons x 8.33 pounds per gallons = 8,330 pounds
1,000 gallons ÷ 7.5 gallons per cubic foot = 133 cubic feet
1,000 gallons x 8.33 pounds ÷ 2.2 pounds per kilogram = 3,785 kg
Note: 1 liter = 1 kilogram therefore, 3.785 liters = 1 gallon
Fill in the blank:
The volumetric capacity of a 5-foot diameter half-sphere is ______ gallons.
245
0.2618 x 5 x 5 x 5 = 32.7 cubic feet x 7.5 = 245.25
Fill in the blank:
The total weight of a water filled 21-foot length of 2-inch Schedule 40 steel pipe is ______ pounds.
108
1.453 + 3.690 = 5.143 x 21 = 108 pounds
Fill in the blank:
The total weight of a water filled 10-foot length of 4-inch Schedule 40 steel pipe is ______ pounds.
164
5.512 + 10.9 = 16.412 x 10 = 164 pounds
Fill in the blank:
A contractor has several lengths of Schedule 40 steel pipe remaining after completing a project. The contractor lists all remaining lengths to be picked up from the project.
2 - 10’ lengths of 2” pipe
7 - 21’ lengths of 2” pipe
3 - 10’ lengths of 3” pipe
4 - 21’ lengths of 3” pipe
12 - 4’ lengths of 1” pipe
The weight of the Schedule 40 steel pipe to be picked up from the project is ______ pounds.
1,570
2 x 10 x 3.690 =73.80 7 x 21 x 3.690 =542.43 3 x 10 x 7.660 =229.80 4 x 21
x 7.660 =643.44 12 x 4 x 1.690 =81.12 1,570.59
Fill in the blank:
When multiplying decimeters times decimeters times decimeters, the end result is ______.
10, 100 or 1,000
3 dimensional is cubic volume
Fill in the blank:
A waste oil tank that is 3’3” in diameter and is 6’4” long, will hold ______ gallons of waste oil.
391
V = .0408 x D” x D” x H” .0408 x 39 x 39 x 6.33 V = 392.82
Fill in the blank:
A lead roof boot with a 5-inch hole that is 18 inches high and has a flat plate area of 18”x18” requires ______ square feet of lead to make.
4.1
Cylinder = 18 x 3.14 x 5 = 282.”
Plate = 18 x 18 = 32”
Subtract hole 3.14 x 2.5 x 2.5 = 19.” 282.6 + 324 – 19.6 = 58 587 ÷ 144 = 4.08
Fill in the blank:
