Energy that causes a transfer of heat between marterials

1 answer:

4 0

Thermal radiation is a form of heat transfer because the electromagnetic radiation emitted from the source carries energy away from the source to surrounding (or distant) objects.

I tried, but I hope this helps :)

Answer:

Geological engineers can help determine if the soil and structural stability in the building's location are satisfactory.

Explanation:

Geologic Engineering refers to a job which applies geology to engineering. This type of job focuses on the investigation of sites in response to soil, rock and groundwater. They help design the major structures for engineering works, thus, it is also their role to know whether the building's soil and structural stability are satisfactory. They determine how much of the structure is a safe load for the soil it is standing upon. They also test the strength of both rock and soil at different depths. This will help them know whether the location will be suitable for the skyscraper.

Answer: Option(d)

Explanation:

Interpersonal skills are a set of behavioral action that involves the person to interact freely with other peoples effectively.

In the above answer, the construction manager has to develop interpersonal skills to resolve the issues, conflicts, and arguments raised by his employees.
The manager must listen to their needs and demands possessed and should take necessary action in resolving the issues.
For that, the manager has to interact freely and effectively with their employees in resolving the issues.

At a certain location, wind is blowing steadily at 10 m/s. Determine the mechanical energy of air per unit mass and the power ge

ale4655 [162]

Answer:

a) 50 J/kg

b) 721 67 KW

Explanation:

The velocity of the wind v = 10 m/s

diameter of the blades d = 70 m

efficiency of the turbine η = 30%

density of air ρ = 1.25 kg/m^3

The area of the blade A = $\pi d^2/4$

A = $\frac{3.142 * 70^2}{4}$ = 3848.95 m^2

The mechanical energy air per unit mass is gives as

e = $v^2/2$ = $\frac{10^2}{2}$ = 50 J/kg

Theoretical Power of the turbine P = ρAve

where

ρ is the density of air

A is the area of the blade

v is the velocity of the wind

e is the energy per unit mass

substituting values, we have

P = 1.25 x 3848.95 x 10 x 50 = 2405593.75 W

Actual power = ηP

where η is the efficiency of the turbine

P is the theoretical power of the turbine

Actual power = 0.3 x 2405593.75 = 721678.1 W

==> 721 67 KW
