A client wants Mila’s team to maximize the energy efficiency of their new office building. The client is interested in acquiring

a large plot of land for the new building in a suburban area north of a major city. From the city, the main access to this area is by a couple of major roads that have heavy traffic at almost all times of day. The client’s current building is easier to access and large enough for projected staffing needs, but it is also old, ugly, and high in maintenance costs. How should Mila’s team best approach this project while adhering to principles of green building?
Agree to build on the land the client is interested in acquiring and concentrate on maximizing the efficiency advantages of the new building.

Persuade the client to tear down the existing building instead and build a new high-efficiency building from the ground up in the same spot.

Persuade the client to renovate their existing building both aesthetically and in terms of efficiency and utility of function.

Find a different location for the new building in a more advantageous spot both in terms of transportation access but also in taking advantage of daylighting.

Answer:

Persuade the client to renovate their existing building both aesthetically and in terms of efficiency and utility of function.

Explanation:

Just would not make sense to tear the building down just to rebuild it when it can be restored.

Over [174]

Answer:

Yes, this is completely independent.

Explanation:

Yes, this is completely independent. Even though there are no South American individuals that are majoring in biomedical engineering in this party it is still a completely independent factor. The origin of birth of an individual does not tie them to a specific degree or field of expertise, therefore a South American individual can study anything they want including mechanical engineering, electrical engineering, or biomedical engineering.

Air flows steadily and isentropically from standard atmospheric conditions to a receiver pipe through a converging duct. The cro
Liula [17]

Answer:

The answer is "0.0728"

Explanation:

Given value:

P_0= 14.696\ ps\\\\\ p _{0}= 0.00238 \frac{slue}{ft^{3}}\\\\\ A= 0.05 ft^2\\\\\ T_0= 59^{\circ}f = 518.67R\\\\\ air \ k= 1\\\\ \ cirtical \  pressure ( P^*)=P_0\times \frac{2}{k+1}^{\frac{k}{k-1}}\\

                                     = 14.696\times (\frac{2}{1.4+1})^{\frac{1.4}{1.4-1}}\\\\=7.763 Psia\\\\

if P flow is chocked

if P>P^{*} \to flow is not chocked

When  P= 10 psia < P^{*} \to not chocked

match number:

\ for \ P= \ 10\ G= \sqrt{\frac{2}{k-1}[(\frac{\ p_{0}}{p})^{\frac{k-1}{k}}-1]}

                       = \sqrt{\frac{2}{1.4-1}[(\frac{14.696}{10})^{\frac{1.4-1}{1.4}}-1]}

M_0=7.625

p=p_0(1+\frac{k-1}{2} M_0 r)^\frac{1}{1-k}

  =0.00238(1+\frac{1.4-1}{2}0.7625`)^{\frac{1}{1-1.4}}\\\\\ p=0.001808 \frac{slug}{ft^3}

\ T= T_0(1+\frac{k-1}{2} Ma^r)^{-1}\\\\\ T=518.67(1+\frac{1.4-1}{2} 0.7625^2)^{-1}\\\\\ T=464.6R\\\\

\ velocity \ of \ sound \ (C)=\sqrt{KRT}\\\\

                                    =\sqrt{1.4\times1716\times464.6}\\\\=1057 ft^3\\\\

R= gas constant=1716

m=PAV\\\\

    =0.001808\times0.05\times(Ma.C)\\\\=0.001808\times0.05\times0.7625\times 1057\\\\=0.0728\frac{slug}{s}

A gas turbine has a thermal efficiency of 20% and develops a power output of 8 MW. Determine the fuel consumption rate if heatin
AlexFokin [52]

Answer:

0.8 kilograms of fuel are consumed each second.

Explanation:

As turbines are steady-state devices, the thermal efficiency of a turbine is equal to the percentage of the ratio of the output power to fluid power, that is:

\eta_{th} = \frac{\dot W}{\dot E} \times 100\,\%

The fluid power is:

\dot E = \frac{\dot W}{\eta} \times 100\,\%

\dot E = \frac{8\,MW}{20\,\%}\times 100\,\%

\dot E = 40\,MW

Which means that gas turbine consumes 40 megajoules of fluid energy each second, which is heated and pressurized with help of the fuel, whose amount of consumption per second is:

50\,\frac{MJ}{kg} = \frac{40\,MJ}{m_{fuel}}

m_{fuel} = 0.8\,kg

0.8 kilograms of fuel are consumed each second.
