The parties in the construction of an earthfall dam for irrigation who will be responsible for the following services are given below.
What is the justification for the above response?Providing labor: The responsibility for providing labor in the construction of an earthfill dam for irrigation will typically fall on the contractor or construction company that has been awarded the contract for the project. The contractor is usually responsible for hiring and managing all the necessary labor, including skilled and unskilled workers, to complete the construction of the dam.
Funding the construction of the dam: The responsibility for funding the construction of the earthfill dam will usually lie with the party or parties that have commissioned the project. In most cases, this will be a government agency or a private company that is investing in the construction of the dam.
Approving the drawings: The responsibility for approving the drawings for the earthfill dam will typically fall on the government agency or private company that is commissioning the project. The drawings will need to be approved by the relevant regulatory bodies and local authorities to ensure that the dam meets all the necessary safety and environmental standards.
Overall coordination of the project: The responsibility for the overall coordination of the project will usually fall on the project manager or project team that has been appointed by the commissioning party. The project manager will be responsible for overseeing all aspects of the project, including managing the budget, scheduling, and ensuring that the construction work is completed to the required standards.
Setting up coordinates and levels for back-filling: The responsibility for setting up the coordinates and levels for back-filling will typically fall on the engineering team that is responsible for the design and construction of the dam. The engineering team will be responsible for surveying the site and determining the best locations for the dam, as well as setting the appropriate coordinates and levels for the back-filling process.

Explanation:
3–109E A 0. 083-in-diameter electrical wire at 90°F is covered by 0. 02-in-thick plastic insulation (k = 0. 075 Btu/h·ft·°F). The wire is exposed to a medium at 50°F, with a combined convection and radiation heat transfer coefficient of 2. 5 Btu/h·ft2·°F. Determine if the plastic insulation on the wire will increase or decrease heat transfer from the wire. Answer: It helps
The heat transfer rate with insulation is significantly higher than the heat transfer rate without insulation, as can be shown by comparing the two heat transfer rates.
Which has the greatest rate of heat transfer?The table shows that solids (s) generally conduct heat at rates that are significantly higher than those of liquids (l) and gases (g).
The following equation can be used to determine the heat transfer rate without insulation under the conditions of steady-state heat transmission and little heat generation in the wire:
A = pidL A = pi0.0831 = 0.26 square inches. Q = hA(T wire - T inf).
Q = 2.50.26(90 - 50) = 26 Btu/h without insulation R = 0.02 / (0.075×0.26) = 0.98 hrft2°F/Btu
Copper, which is frequently used for electrical cables, has a thermal conductivity of roughly 223 Btu/hft°F. Inputting the values provided yields:
R total = 1 / (2230.26pi×0.0832 / 4) = 0.14 hours/feet/degrees Fahrenheit/Btu
We obtain the following by substituting the above values: q with insulation = (90 - 50) / 0.14 = 286 Btu/h
